🚀 The Tech Revolution in Ultramarathons
In 2025, ultrarunning isn’t just about grit—it’s about gear, guidance, and GPS. 🛰️🏃♂️ As courses grow wilder and runners seek more remote challenges, the rise of ultramarathon navigation technology has become impossible to ignore.
Whether you’re racing a 100-miler through alpine terrain or fastpacking across the desert, chances are high you’ll be depending on some form of tech: a GPX route on your watch, a trail safety app, or a wearable with solar charging and live tracking. These tools are now as essential as your shoes or fuel.
📈 In fact, at several 2024 races, over 90% of participants relied on GPX navigation during the event—highlighting how mainstream it has become in ultra-distance racing.
But here’s the kicker: more tech doesn’t always mean more safety. A dead battery, a mistimed signal drop, or blind reliance on a device can still spell disaster. That’s why smart runners don’t just own the gear—they train with it, test it, and prepare for it to fail.
In this comprehensive guide, we’ll dive into the best trail running safety apps 2025, explore cutting-edge GPS and wearable tech, and help you build a navigation and safety strategy that works when it counts.
Let’s plug in—and then learn when to unplug. ⚡🧭
🛰️ 1. Why GPX Navigation Became Standard
Not long ago, ultrarunners would memorize trail markers, trust course ribbons, or follow the pack. But in 2025, things have changed. From local 50Ks to iconic 100-milers, GPX route ultra running has become the new normal.
In fact, at one recent U.S. ultra event, over 90% of runners used GPX files on their GPS watches for navigation. Why? Because ultramarathon navigation technology isn’t just about convenience anymore — it’s about staying safe, efficient, and in control.
📍 What Is a GPX File (and Why Should You Care)?
GPX (GPS Exchange Format) files are digital maps of the race route — including every turn, fork, elevation change, and checkpoint. You can load them onto your:
- 🕶️ GPS Watch (Garmin, Coros, Suunto)
- 📱 Smartphone apps (like Gaia GPS, AllTrails, Komoot)
- 🧭 Dedicated handheld navigators
Once loaded, you’ll see a breadcrumb trail overlaid on your screen — guiding you through every twist of the course, even when the fog rolls in or the course markings get stolen (yes, it happens!).
⚡ 6 Reasons GPX Has Taken Over Trail Ultras
- 🚫 No More Getting Lost
Even if course flags blow away, your wrist map stays put. - 📵 Works Without Cell Signal
Most GPS devices run offline — perfect for remote races. - 🧠 Mental Relief
Focus on your pace, hydration, or terrain — not “Did I miss that last turn?” - 🔁 Instant Rerouting
Strayed 50 meters off-course? Your watch tells you instantly. - 💾 Course Previewing
Download in advance, study elevation gain, key aid stations, or dangerous turns. - 📏 Post-Race Analysis
Use the GPX data for review, comparison, or bragging rights 😎
🧠 Boss Tip: “Tech Should Guide, Not Decide”
While GPX files are powerful, overreliance is risky. Glitches happen. Devices freeze. Batteries die. Always carry:
- 🗺️ A physical map (if provided by race)
- 🧵 A rough mental idea of the course layout
- 🔋 Spare battery or power bank (you’ll thank yourself at mile 80)
🏁 Real Runners, Real Saves
“I missed a trail split at mile 42. My watch buzzed: ‘Off Course!’ — I backtracked just in time. Without that, I would’ve added 6 miles.”
— Logan P., Bigfoot 100 Finisher
“The fog was so thick, I couldn’t see markers. But my GPX track kept me going — straight into a Top 10 finish.”
— Sarah M., Orcas Island 50K
As you can see, GPX navigation is no longer optional — it’s the new standard in trail running safety apps for 2025. Whether you’re chasing cutoffs or exploring new terrain, your GPX file is your digital trail buddy.
🛠️ 2. Creating & Editing GPX Routes for Races
So you’ve heard that GPX navigation is the future — but where do those magical files come from? And how can you customize them for your own training or race prep?
Let’s break it down: creating, editing, and optimizing your own GPX routes can unlock next-level confidence and control — especially in races where navigation is self-supported or where course info is limited.
🌐 Where to Find Official GPX Files
Some race organizers now provide official GPX files on the event website or via email. Always start there. But if not, you can usually build one yourself using:
- Strava Routes – Great for visual editing & elevation
- Gaia GPS – Highly detailed topographic mapping
- Komoot – Popular in Europe, great for trail-specific detail
- CalTopo – Ideal for layering multiple map types
- AllTrails – Good for popular trail previews
You can also grab past participants’ routes on Strava or Wikiloc — just make sure they match the current year’s course.
✍️ How to Edit or Customize a GPX File
Sometimes you’ll want to:
- 🚫 Remove sections (like warm-up or cool-down parts)
- 🔁 Add in water stops or crew checkpoints
- 🗺️ Smooth out GPS noise or adjust start/end points
Here’s how:
- Download the GPX file
- Upload it into a tool like GPX Studio, RideWithGPS, or Garmin Connect
- Edit the points, trim extras, mark key spots (aid stations, junctions, etc.)
- Re-export your cleaned-up GPX for use on your watch or app
🎯 Pro Tip: Use route color-coding if your app allows it. For example:
Red = climb zones, Blue = water stops, Yellow = tricky nav spots.
📥 How to Load a GPX to Your GPS Watch or App
- Garmin: Use Garmin Connect (web or mobile)
- Coros: Sync via Coros app route builder
- Suunto: Use Suunto App → Navigation → Routes
- Wahoo, Polar, etc.: Typically support import via their mobile app or online dashboard
💡 If you’re racing in airplane mode or no-signal zones, make sure to pre-download maps and test them in training.
🧠 Boss Reminder: Plan, But Also Preview
A good GPX file isn’t just a safety net — it’s a strategic advantage. Before your race:
- Zoom in on elevation spikes
- Study key decision points (turns, trail forks)
- Mark where aid stations are — and plan fuel strategy accordingly
🏃 Real-Life GPX Power Moves
“I added aid station markers to my file — and it reminded me to fuel on time, not just when I felt tired.”
— Nico R., Javelina 100
“We mapped our own GPX from scouting the trail a month early. During the race, it saved us after course tape was blown away by wind.”
— Ellie T., Fat Dog 120
🔚 Whether you’re racing or training, knowing how to build your own GPX route gives you independence, confidence, and a serious edge. Plus — let’s face it — it feels awesome to load a custom route you designed yourself.

✅ Offline Use is Powerful
Download the entire route + surrounding area before race day, and you’re ready even without signal.
✅ Easy Input & Edits
Need to adjust your route the night before the race? Way easier on a touchscreen.
✅ Cheaper than a $700 GPS Watch
Already have a decent phone? Just download the right app and you’re in business.
⚠️ Cons of Relying Solely on Phones
❌ Battery Life Is a Gamble
Even in airplane mode, a screen-on GPS session drains battery fast. You’ll need:
- Power bank (at least 5000 mAh)
- Charging cable
- Possibly solar charger for multi-day races
❌ Risk of Drops, Rain, or Glove Hassles
Try operating your phone at 3 AM in freezing wind with numb fingers. It’s a vibe. A bad one.
❌ Too Many Distractions
Text alerts, social media pings, or even music apps can break your focus if not fully disabled.
❌ Bulky & Fragile
Phones aren’t optimized for one-handed use on rugged trails. One bad fall and it’s race over (and possibly phone over too 📉📱).
🧠 Boss Strategy: Phone = Brain, Watch = Reflex
Use your phone for pre-race planning and map previews, but lean on your watch during the actual race. Here’s how:
- 📲 Use your phone to study trail sections at night or during rest breaks

📦 Bonus: Some phones now support satellite emergency messaging (e.g., iPhone 14/15). In remote terrain, this can be a lifesaver. Literally.
Final Word: Use your smartphone as a powerful navigation backup and planning device, but don’t depend on it like your legs. For real-time pacing and hands-free alerts, your watch is still king. 👑
🧯 5. What to Do When Tech Fails Mid-Race
You’re cruising through mile 47. The fog’s thick, the trail’s remote — and suddenly…
💥 “Low Battery”
💥 “Route Unavailable”
💥 “Device Shutdown”
Yep, it happens. Even the best gear crashes, batteries die, and connections fail. That’s why smart ultrarunners don’t just use tech — they plan for when it disappears.
Here’s what to do when your ultramarathon navigation technology fails in the middle of a race.
🔋 First, Let’s Talk Battery Failures
If your GPS watch dies mid-race:
- 🧠 Stay Calm. Don’t Panic.
You’re still the engine. You’re still moving. Just slower — and smarter. - 🔋 Plug In a Power Bank ASAP
Many watches can charge while running (check model specs). Use a short cable + tuck it under your sleeve or vest. - 📲 Switch to Phone Navigation
If your watch is down, your phone becomes plan B. Load your GPX route on Gaia, Komoot, or AllTrails. - 🗺️ Use Trail Cues
Remember those landmarks you studied pre-race? Time to trust them.
💥 If You’re Totally Without Navigation
Let’s say: dead watch, no phone signal, no clue. What now?
✅ Check for Runners Nearby
Follow someone you trust — ideally someone with a visible nav device.
✅ Ask Volunteers at Aid Stations
Most have printed maps or can describe the next segment. Don’t be shy.
✅ Trust Flagging – but with Caution
If markings seem inconsistent or missing, stop. Backtrack to the last confidence point.
✅ Use Common Sense Terrain Navigation
– Stay on the most-worn path
– Avoid random side trails
– Listen for aid station sounds, headlamps at night, cowbells (yes, they still exist)
📦 The Boss-Approved Tech Failure Kit:
- 🔌 Short USB charging cable
- 🔋 Mini power bank (3000–5000 mAh)
- 📃 Printed map or course profile in ziplock
- ✍️ Route notes: tricky turns, aid station distances
- 🧠 Mental backup plan (you’ll use this more than you think)
🧠 Boss Truth: Tech Doesn’t Win Races — You Do
“My Coros froze at mile 62 in the Alps. I panicked… but then I remembered: I’d memorized the course segments. I found flags, refocused, and finished 6th overall.”
— Helena W., Eiger Ultra Trail
“The screen went black, but I still had my printed map. It wasn’t perfect, but it kept me calm.”
— Luis J., Lavaredo 120 finisher
💡 Train your brain like a device.
Know the route. Know your body. Know your backups.
Because when technology fails — the real ultrarunner shows up. 💪🧭

🧠 Boss Rules for Safe Running in the Wild
- If You Can’t Carry It, You Don’t Own It
Gear in your drop bag doesn’t help when you’re 20 miles from it. - Don’t Skimp on Visibility
A reflective vest at night can be the difference between runner spotted and runner lost. - Test in Training
Never race with gear you haven’t tested. A rubbing pack strap at mile 12 turns into agony at mile 60.
🐻 Wildlife Encounter Basics
Ultra trail = ultra wilderness. Here’s the quick survival playbook.
🐻 Bears (especially in North America)
- Don’t surprise them: wear a bell, make noise on blind turns
- Back away slowly if seen — don’t run
- Carry bear spray in grizzly territory
🐍 Snakes
- Watch where you step — especially near rocks
- Use poles to tap trail ahead in brushy areas
- Don’t try to move or touch a snake (seriously, boss)
🦌 Big Game (Elk, Moose, etc.)
- Give space. Lots of it. They can charge.
- Stay calm and don’t look them in the eye
- If in rutting season (fall), be extra alert
💬 Real Runners, Real Saves
“I got stung at mile 10, allergic reaction started fast. I had Benadryl in my mini kit. Without it, DNF or hospital.”
— Marco T., Mountain Lakes 100
“Rain hit HARD. Everyone else froze. I had a poncho and gloves. Passed 6 runners in that storm.”
— Julie R., UTMR finisher
📦 Final Mini-Survival Checklist:
- 🔋 Charged GPS watch
- 🛡️ Emergency blanket
- 🗣️ Whistle or bell
- 💧 Purification tabs
- 🩹 Blister kit + antihistamine
- 🧢 Buff, gloves, light shell
- 🐍 Trail sense
📌 TL;DR: You don’t need to carry a tent… but you do need to respect the wild.
Run light, but not foolish. The mountain doesn’t care how fast you are — just how prepared you are.
🌐 12. Using Tech in International or Multi-Day Ultras
Running a 100-miler is hard.
Running one across borders, time zones, and languages?
That’s next level — and tech is your best ally.
From stage races in the desert to alpine ultras in Europe, here’s how to adapt your gear, navigation, and safety strategy when racing far from home.
✈️ Tech Packing List for Global Ultra Travel
| Item | Why It’s Crucial |
|---|---|
| 🕶️ Dual-voltage USB charger | Global plug types vary — be ready |
| 🔌 EU/UK/Asia power adapters | Don’t get caught with a dead power bank |
| 🌍 Pre-downloaded offline maps | Cell signal may be nonexistent |
| 🧭 Watch with multilingual interface | English-only menus may be limiting |
| 💬 Translation app (offline mode) | Talk to aid crews or read race signs |
| 📄 Printed GPX + elevation profiles | Especially useful if phone fails or in non-English environments |
💼 Bonus: Carry all charging gear in carry-on, not checked luggage. Luggage delays can leave you tech-less on race day 😱
🧭 Navigation in Foreign Terrain
- ❄️ Running the Alps? Weather can change in 5 minutes — maps and elevation are more important than pace.
- 🐫 Sahara Stage Race? Heat kills batteries. Use low-power modes + lightweight solar banks.
- 🌳 Jungle ultras? GPS signal may flicker. Download detailed offline maps with trail overlays.
🎯 Boss Hack: Use CalTopo or Gaia GPS to layer elevation, slope angle, vegetation, and hydrology for any country. Then sync to your watch.
🌐 Dealing with Language Barriers
Most runners worry about:
- ❌ Aid station labels (water? electrolyte? broth?)
- ❌ Emergency communication (“I’m injured!”)
- ❌ Getting directions when lost
💬 Use a translation app like Google Translate in offline mode
📸 Snap a photo of aid signs + translate text instantly
🗣️ Practice essential phrases: “Help”, “Food”, “I’m lost”, “Where’s aid station?”
“I was in Italy, couldn’t read signs. Used the camera translator to find out the ‘Coca’ was actually chicken broth. Saved my stomach!”
— Lena R., Lavaredo 120
📡 Tech Connectivity Abroad
- 📱 Get a local SIM card or eSIM if you need data access
- 📵 Otherwise, go full airplane mode + rely on downloaded content
- 💰 Avoid roaming charges — download everything before leaving your country
- 🗺️ Test all apps with no internet before race day (don’t assume they’ll work offline!)
🧠 Boss Travel Tips for Tech
- Backup your GPX files to cloud + USB stick
- Label cables (yes, really) – Everyone’s charger looks the same at the hotel
- Practice gear packing — know exactly where your nav device, charger, and backup battery are mid-race
- Notify family/crew of time zone difference for live tracking
🏁 Stage Race Considerations
In multi-day ultras (like Marathon des Sables, TransRockies, or Ultra X):
- 🎒 Battery conservation is critical — no wall chargers on trail
- 🔋 Consider solar power banks + ultra-low-power GPS modes
- 📦 Use tech to log recovery: HRV, sleep, hydration tracking
- 🛏️ Download race briefings or course changes in advance each day
“We had no Wi-Fi in the desert. I used my GPS watch + solar bank + downloaded maps to stay on course all 6 days.”
— Ben M., Marathon des Sables
📌 Final Word: In foreign ultras, tech can be your translator, navigator, lifeline, and recovery coach. But only if it’s prepared, tested, and travel-ready.
Don’t let a plug adapter or signal bar be the reason you DNF.
📈 13. Data-Driven Training with GPS & Wearables
You’ve got a watch. It counts your steps.
You’ve got a chest strap. It reads your heartbeat.
You’ve got a power pod. It tracks your watts.
Cool. But… now what?
Welcome to the age of data-driven ultramarathon training — where your gear doesn’t just collect numbers… it coaches you, paces you, and protects you from injury.
Let’s unlock the full power of your devices. 🧠⚙️
🕶️ What Wearables Are Telling You (If You’re Listening)
| Metric | What It Means | Why It Matters |
|---|---|---|
| 🏃♂️ Pace & Speed | How fast you’re moving | Core for intervals, race planning |
| 📍 Cadence | Steps per minute | Low = fatigue or risk of injury |
| ⚡ Running Power | Energy output in watts | More stable than pace on hilly terrain |
| ❤️ Heart Rate | Internal effort level | Avoids overtraining, manages fatigue |
| ⏱️ Heart Rate Variability (HRV) | Recovery & stress score | Low HRV = time to rest |
| 💤 Sleep Tracking | Duration + quality | Foundation of all recovery |
| 🔄 Ground Contact Time / Balance | How you move | Great for form correction |
🎯 Boss Setup: Essential Devices for Data Training
- ⌚ GPS Watch (Garmin, Coros, Suunto)
- ⚡ Running Power Sensor (e.g. Stryd)
- ❤️ Chest Strap HR Monitor (more accurate than wrist)
- 📱 Companion App (Garmin Connect, TrainingPeaks, Stryd, HRV4Training)
💡 Bonus: Use platforms like Final Surge or AI-based tools (Athlytic, Elevate, Runalyze) to interpret your raw data smarter.
🧠 Interpreting Your Metrics Like a Pro
“Why do I care about power?”
Power shows effort independent of terrain or weather. If you’re pushing 300W uphill and 250W on the flats — you’re being smart.
✅ Train by power on trails = better pacing, fewer bonks.
“What’s a good cadence?”
Most elite trail runners hit 170–185 spm. If yours is 155, you may be overstriding.
✅ Slight cadence increase = less injury risk.
“How do I use HRV?”
Low HRV = high stress = REST.
✅ Use HRV to adjust weekly load. Track trends — not just single values.
📊 Example: Weekly Training Dashboard Snapshot
📊 Weekly Training Dashboard
- Average Power: 265W (up 2.5%)
- HRV Avg: 61 → 55 (possible fatigue)
- Sleep Quality: 6.5/10 (improve this!)
- Long Run: 2h 40min @ 72% HR Max
- Cadence: 174 avg (strong form!)
- Ground Contact Imbalance: 51/49 (excellent)
You just became your own coach.
🧠 Boss Principle: Track less, analyze smarter.
Don’t drown in numbers. Focus on:
- 🚦 Load vs Recovery balance
- 📉 Fatigue warning signs
- 🎯 Power-based pacing for long races
- 📆 Trend lines over time — don’t freak at daily blips
“I used to train by feel. Now I train by data, rest by data, and win by combining both.”
— Arif T., Cappadocia Ultra-Trail top 10
📌 Final Word: Your GPS watch isn’t just a timer — it’s your coach, physiologist, and data scientist.
Use it like a pro. And remember: Numbers don’t lie… but they do need context.
🧠 14. Overreliance on Technology: Is It Making Us Weaker?
We train by GPS.
We pace by power.
We rest by HRV.
We fuel by alerts.
But here’s the question — are we still listening to ourselves?
As tech becomes the ultra runner’s best friend, it’s easy to forget who’s actually doing the running. In this part, we ask the uncomfortable question:
Is relying too much on technology making us mentally softer, physically lazier, or even more vulnerable?
Let’s dig in.
🤖 Signs You Might Be Over-Tech’d
- 😵 You freeze when your watch dies mid-run
- 📉 You ignore your body because your “data looks fine”
- 🤖 You don’t know how to pace without a screen
- 🧭 You’ve never navigated a trail without GPX
- 📱 You need a phone alert to remind you to eat
It’s not weakness — it’s habit. But habits can be upgraded.
🧠 Ancient Tools Still Work
Before GPS, runners used:
- ⏳ Effort-based pacing: “I can talk, so I’m in zone 2.”
- 🧭 Trail reading: “That ridge lines up with the sun.”
- 💧 Thirst and hunger cues: “I’m dizzy. I need sugar.”
- 🩺 Body signals: “My stride’s off — maybe I need salt.”
- 📅 Journaling recovery: Not HRV, just how they felt.
Now we call this “primal running,” but it’s not primitive — it’s resilient.
🧠 Boss Analogy: Tech Is Like a Car’s Dashboard
Think of your GPS and wearables like the dashboard of a car.
- 🛞 Pace = speedometer
- 💧 Fuel gauge = hydration level
- ⚠️ HRV = check engine light
- 🧭 GPX = navigation screen
But just like driving, if you only look at the dashboard and not the road, you’re gonna crash.
Look up. Feel the terrain. Trust your gut.
Then use tech to refine what your body already knows.
🧘 Build Internal Awareness Alongside External Tools
| External Tech | Internal Skill to Rebuild |
|---|---|
| 🏃♂️ GPS Pace | Run by feel (RPE scale 1–10) |
| 📉 Power Meter | Recognize uphill effort vs flat effort |
| ⏱️ HR Data | Notice breath rhythm & heat signs |
| ⏰ Nutrition Timers | Tune into hunger/cramp onset |
| 🗺️ GPX Nav | Learn how to read a trail junction intuitively |
💬 Runners Who Found Balance
“I used to panic when my watch glitched. Now, I run tech-free once a week — it sharpened my instincts.”
— Maya D., Ultra Fiord finisher
“My HRV was green, but I felt wrecked. I skipped my session. That choice saved my race 3 days later.”
— Colin B., UTMB finisher
“I learned to pace by breathing — now my data matches my feel. That’s power.”
— Arda K., Mount Olympus Ultra
🔁 Boss Challenge: Go Device-Free… Sometimes
- One tech-free easy run per week
- One navigation-only hike without GPX
- One long run where you eat by feel, not schedule
- Write a short post-run journal — how did it really feel?
You’ll be amazed how sharp your instincts become again.
🏆 15. Tech Habits of Elite Ultra Athletes
What separates elite ultrarunners from the rest?
It’s not just mileage, VO₂ max, or shoe sponsors.
It’s how they use tech — intentionally, intelligently, and only when it serves performance or recovery.
Let’s peek into the digital toolkits of the world’s best ultra athletes and see what you can steal (legally 😎).
🔁 Tech Isn’t Obsession — It’s Strategy
Top athletes don’t chase every shiny gadget. They focus on:
- 📊 Key metrics that directly influence performance
- ⌛ Time-saving tools that automate tracking and feedback
- ⛔ Tech boundaries — they know when to unplug
It’s not “how much tech,” but “what kind of tech, for what purpose.”
💼 What Elites Actually Use (and Love)
| Tool | How They Use It |
|---|---|
| 🕶️ GPS Watch | Precise pacing, elevation control, night section efficiency |
| ⚡ Power Meter (Stryd) | Dialing in race pace on hilly trails |
| ❤️ HR Monitor (chest strap) | Aerobic threshold tracking, fueling precision |

| 🧭 GPX Nav + Printed Map | Double-layer backup for high-stakes races |
| 🧠 Data Platform (TrainingPeaks, Final Surge) | Review + communicate with coaches |
“I track power on every run, but I don’t obsess. If I feel good, I go. If I’m tired, I back off — even if power says I can push.”
— Fernanda M., elite mountain runner
⛔ What They Don’t Rely On
- 📱 Phone nav during racing (too distracting)
- 📥 Every metric — they focus on a few
- 🔋 Charging mid-run (they pick watches that last the whole race)
- 🎧 Constant audio cues (they prefer silence to focus on effort)
🎯 Minimal tech, maximum focus.
🎓 What Makes Their Approach Different
1. Pre-race simulation:
They don’t just train their body — they train tech scenarios.
– Watch freeze?
– GPX reload under stress?
– Battery top-up with gloves?
2. Post-run analysis ritual:
– Power curve tracking
– HR decoupling trends
– Cadence vs terrain reports
3. Data is feedback — not gospel:
They listen to the body first, data second.
“Sometimes, my HRV says I’m ready, but I just feel flat. I learned to take a walk instead. Long-term gains win races.”
— Aidan T., 100-mile podium finisher
🧠 Boss Breakdown: How You Can Copy Elite Tech Habits
| Elite Move | Your Version |
|---|---|
| 🎯 Narrow focus | Pick 2 key metrics only (e.g., HRV + Power) |
| 🛠️ Tech drills | Practice using GPX + recharging mid-run |
| 📆 Data calendar | Weekly 15-min review instead of daily obsessing |
| 💤 Track sleep | With any wearable — trends matter |
| 💬 Debrief solo | Journal feel vs. numbers every Sunday |
📌 Key Takeaways
- 🧠 Elites don’t use more tech. They use it better.
- ⏱️ They train for data just like they train for distance.
- 💡 You can too — with the right tools, the right mindset.
🔮 16. Augmented Reality and Route Visualization (Future Peek)
In the near future, your ultramarathon might look a lot different. Imagine this:
You’re running up a steep climb, your GPS watch beeps with an alert. But instead of glancing down at your wrist, you look up, and AR glasses project a live map right in front of you. 🚀
In 2025, augmented reality isn’t just for video games and sci-fi movies. It’s starting to change the way we navigate, race, and recover. Let’s take a peek into this cutting-edge tech and how it’ll fit into your ultra future.
🧠 What is Augmented Reality (AR) for Ultra Runners?
Augmented Reality overlays digital information (like maps, directions, elevation, race stats) onto the real world you’re experiencing. Instead of checking your watch for pace, the AR glasses can show your next turn, remaining elevation, and pacing on the trail directly in front of you.
Picture this:
- 🧭 Route Visualization: The trail is shown as a 3D map in your view, showing splits, elevation gains, and any upcoming obstacles.
- 🕹️ Real-Time Stats: Pacing, HR, cadence — all shown in your line of sight, so no more taking your eyes off the trail.
- 🚶♂️ Distance & Time: See how many miles to go and what your next aid station looks like — without checking a watch or phone.
🏞️ How Can AR Change Your Ultra Experience?
- Live Route Overlays
AR can create a 3D projection of the course in front of you, giving you real-time updates on your next turn, the distance, and upcoming hazards (steep drop, loose rocks). - Pacing Adjustments
You’re about to hit a tough climb. AR glasses will show your current pace compared to your target. It’ll even suggest pacing adjustments to meet your goals, helping you stay in the green. - Increased Safety
If you’re running in remote areas, AR glasses can provide emergency alerts. Should you veer off course, your AR system could show a warning, directing you back to the right path in real-time. - Visualization of Aid Stations
Want to know if the next aid station is around the corner? AR glasses can show you upcoming aid stations, hydration stops, or medical tents as they approach, helping you plan for fueling and recovery.
🧠 Boss Vision: Is AR the Future or the Hype?
Here’s the truth: AR glasses for ultrarunning are still in the prototype phase, but they’re rapidly evolving. Several companies are already working on headsets designed for sports navigation, with top contenders including:
- HoloLens by Microsoft
- Google Glass (revamped for sports)
- Vuzix Blade AR glasses
But here’s the catch:
While they’re promising, battery life, field-of-view, comfort, and weather resistance are still challenges. It’ll be a few more years before these glasses are race-ready.
🏃♂️ Future Use Cases: How They’ll Help Elite Athletes
- Speed Navigation in Dense Terrain
Imagine navigating a complex mountain section with dense trees. AR glasses would show visible markers, guiding you with easy-to-follow virtual arrows. - Real-Time Competitor Comparison
Looking for a race edge? AR glasses could compare your current pace and position with top competitors in real-time, helping you make race strategy adjustments on the fly. - Fatigue Monitoring
AR glasses could show calories burned, HR zones, and fatigue levels in real time, allowing athletes to adjust their strategy before hitting a mental or physical wall.
📦 Boss Tip: Don’t Get Obsessed — Use Tech to Enhance, Not Replace
In the same way you shouldn’t rely solely on a GPS watch or HR data, don’t let AR take away your connection to the trail. It’s a tool to enhance, not replace your instincts.
“The best ultrarunners don’t just pace by power or heart rate — they pace by feeling. AR is helpful, but I still trust my legs to get me through tough spots.”
— Nina J., Ultra-Trail du Mont-Blanc finisher
📌 Final Thought
While AR glasses aren’t quite ready to take over the ultra world, they are certainly paving the way for smarter, safer, and more efficient racing. When they hit the market, they’ll provide real-time course feedback that will elevate your strategy, and give you peace of mind in remote areas.
🚀 17. AI-Based Coaching Alerts During Races
We’re officially stepping into the future of ultramarathon coaching — but this time, it’s AI-powered.
Imagine a system that’s tracking every aspect of your race — pacing, heart rate, nutrition, even your mental state — and sending you real-time alerts and advice based on live data. No more waiting until the end of the day for race insights. Now, it’s happening as you run.
In 2025, AI-powered coaching alerts are changing how athletes monitor their performance and make decisions during races.
🤖 How AI-Based Coaching Works
AI coaching platforms (like Stryd, TrainingPeaks, Garmin Coach, RunScribe) work by collecting real-time data from your devices:
- 🧠 Heart rate zones: Alerts when you’re overexerting
- 🏃♂️ Pacing adjustments: Based on terrain, fatigue, and weather
- 🍏 Nutrition guidance: Reminders when you’re falling behind on fueling
- ⏱️ Split times: Instant feedback on whether you’re ahead or behind goal pace
The AI system adapts as the race progresses. It uses machine learning to interpret your data, compare it to thousands of past race profiles, and offer personalized advice — just like a real coach!
💡 Why AI Alerts Are Game-Changing for Ultras
- Real-Time Feedback
Instead of waiting until the race is over, AI sends you actionable alerts in real-time. This can help you avoid burnout, adjust pace, and optimize nutrition during the race. - Personalized Strategies
Traditional advice might say, “Run at 70% of your max heart rate,” but AI coaching considers your unique fitness, course profile, and conditions to give you hyper-personalized recommendations. - Dynamic Course Adjustments
If you’re approaching a steep climb, the AI could tell you, “Slow down for the next 10 minutes” to preserve energy. Or, “Pick up the pace after the descent to make up time.” This level of on-the-fly pacing advice helps maintain consistency in performance. - Mindset Monitoring
Some AI systems even analyze your mental state based on changes in pace, heart rate, and overall fatigue. Alerts like, “It looks like you’re fading, time for a mental boost” could be the difference between quitting and pushing through.
🧠 Boss Tip: Embrace It — But Don’t Forget to Listen to Your Body
While AI coaching can be a game-changer, don’t let it take over completely. Like any tool, it should complement your instincts. Trust your body when it says, “I need to slow down,” even if the AI says, “Push harder.”
💬 Real Runners, Real Success
“During the Marathon des Sables, the AI coach gave me real-time pacing adjustments and reminded me to fuel on time. I felt amazing the whole race.”
— Maria P., 2025 Marathon des Sables Finisher
“I hit a mental block at mile 45. The AI said, ‘You’re in the top 10% for pacing today — keep going!’ It made me believe I could finish strong.”
— Tom B., Leadville 100 Top 10
🚀 AI’s Role in the Future of Ultramarathon Racing
AI isn’t a replacement for physical preparation, but it is the future of smart racing. By offering dynamic feedback during the race, AI coaching helps runners stay on track, optimize their efforts, and push their limits in ways they never thought possible.
📌 TL;DR:
AI-based coaching during races isn’t just science fiction anymore — it’s here.
It gives runners real-time feedback on pacing, nutrition, and mental state, allowing dynamic adjustments during the race. The future is now!
💪 18. Fatigue and Recovery Metrics: Using Wearables to Track and Improve Recovery
You’ve pushed your body to the limit. Your legs are sore, your heart is racing, and your mind feels like mush. But here’s the trick: The race isn’t over when you finish.
In the world of ultramarathon running, recovery is just as important as race day itself. With wearables providing fatigue and recovery metrics, athletes now have data-backed insights to optimize recovery, avoid overtraining, and maximize performance long-term.
🧠 Why Recovery Metrics Matter
Fatigue is a silent killer in ultras. Many runners train too hard and don’t realize they’re running on empty until the race hits. Or worse, they overtrain and face burnout or injury.
That’s where wearables come in. They can track:
- 🏃♂️ Heart rate variability (HRV) – your body’s readiness to recover
- 💧 Hydration levels – ensuring you’re not running at a deficit
- 😴 Sleep quality – how well you’re resting
- 🧘 Stress levels – physical and mental
📊 The Best Wearables for Tracking Fatigue and Recovery
| Device | Key Features | Best For |
|---|---|---|
| Whoop Strap | Tracks HRV, sleep quality, stress, recovery | Ideal for recovery-focused athletes |
| Oura Ring | Sleep tracking, HRV, body temperature changes | Best for sleep and rest-focused data |
| Garmin Forerunner / Fenix | HRV, body battery (energy reserves), stress | Comprehensive tracker for ultra runners |
| Polar Vantage V2 | Sleep, HRV, training load, recovery index | Great for balance of training and recovery |
🧠 What HRV (Heart Rate Variability) Tells You
Your HRV is the time between heartbeats. A high HRV typically means you’re well-rested, while a low HRV means your body is stressed or fatigued. Tracking HRV can be a powerful tool to avoid overtraining, as it provides a readout of your body’s stress.
- Elevated HRV: Your body’s in recovery mode, ready for more intensity.
- Low HRV: Your body’s in a stressed or fatigued state, and you need rest.
“I used to run through low HRV readings, thinking it was fine. After using Whoop for a few months, I started resting more when my HRV was low — I feel better now in every race.”
— Tom F., 50K podium finisher
⚡ Key Recovery Metrics You Should Track
- Sleep Quality and Duration
- 🔋 Your body repairs during sleep, so tracking both quality and quantity is crucial.
- Goal: 7-9 hours of deep sleep and good REM cycles.
- Body Battery (Garmin)
- Body Battery tracks your energy reserves based on activity, sleep, and stress.
- Goal: 60+ for starting a run, and resting at 80-100 for best performance.
- Hydration
- Wearables like the Garmin Venu and Whoop can give you hydration feedback (via sweat rate).
- Goal: Maintain hydration levels throughout the day and during runs. Dehydration can negatively affect recovery and performance.
- Training Load
- Wearables assess your training load and recovery by comparing daily activity with rest levels.
- Goal: Avoid high training loads with low recovery scores.
🧠 Boss Tip: Rest Is Part of the Training
Overtraining is dangerous and counterproductive. It’s essential to incorporate rest days based on data, not just how your legs feel. Trust your wearables to guide your training and recovery balance.
💬 Real Runners, Real Recovery
“I used to push myself through exhaustion. After wearing the Oura ring, I realized my recovery time was too short, and my performance improved when I listened to the data.”
— Lucy S., 100-mile finisher
“By following recovery metrics, I avoided injuries last year. It’s saved me during heavy training weeks.”
— Matt L., Trail running elite
📌 Final Word
Your data-driven approach to fatigue management and recovery can change the way you race and recover. While physical effort will always play a huge role in ultra racing, your recovery will be the deciding factor in whether you break through your personal best or hit the dreaded wall.
🛡️ 19. Building a Personal Safety Protocol for Remote Races
When you step into the unknown, whether it’s a mountain ultra, desert stage race, or off-grid trail, your personal safety protocol will be the difference between finishing strong and being forced to call for help.
In 2025, more and more runners are choosing remote, unsupported ultras, which means you need a self-sufficient, safety-first approach that can handle anything — from getting lost to injuries, weather changes, and even dehydration.
Let’s break down how to prepare for the worst-case scenarios, and make sure your race doesn’t turn into a rescue mission.
🧭 Your Personal Safety Protocol: Must-Have Elements
| Element | Why You Need It |
|---|---|
| 🗺️ Backup Navigation | Never rely on one GPS device or phone app. Carry offline maps + GPX backups on your watch and phone. |

🧠 Mental Safety: Don’t Panic
Your tech fails, you’re in the middle of nowhere, and you feel the fatigue hit. Panic can make you do crazy things (like running in the wrong direction or pushing too hard). Mental clarity is key:
- Breathing exercises to calm your mind
- Focus on small steps and short-term goals (e.g., reaching the next aid station)
- Trust your pre-race plan — stick to it as much as possible
- Know your emergency contacts and race exit options
“When I hit the mental wall at mile 80, my Garmin inReach had me mapped to a short exit route. That safety plan kept me moving.”
— Luis T., Western States finisher
⚡ Tech Tools for Safety You Might Not Think Of
- Whistle or Bear Bell: Perfect for wildlife awareness. You might not need it often, but when you do — it’s a game-changer.
- Solar Chargers: Keep your phone or GPS running in ultra-long races. You never know when you’ll need to make an emergency call.
- LED Lights: For visibility during dark night sections — better safe than sorry.
💬 Boss Tip: Know Your Limits, Know Your Plan
The best runners never stop training their safety protocol. Practice emergency drills, understand the terrain before race day, and have a mental game plan. If something goes wrong, you’ll be ready.
📌 Final Word
In remote races, preparation is everything. The course may be remote, but with the right tech, training, and mindset, you can ensure that you’re always in control of your safety, no matter what comes your way.
🚑 20. Emergency Protocols: When the Worst Happens During a Race
