At first glance, it seems almost simple: Run a 4.167-mile (6.706 km) loop every hour, on the hour. Finish within 60 minutes? Great. You’re allowed to start the next lap. Don’t make it? You’re out. Keep going until there’s only one runner left standing — the Last Person Standing. 🏆
This is not your ordinary ultramarathon. There’s no set distance, no finish line, no cutoff time. Just an ever-repeating loop. It’s a mind game, a test of rhythm, resilience, and resolve.
Invented by the legendary Lazarus Lake (yes, the same mind behind the Barkley Marathons), the Backyard Ultra format began with Big’s Backyard in Tennessee — named after his dog. Since then, it has become a global phenomenon, with national championships, world championships, and thousands of runners pushing their limits in loops of mud, sweat, and hallucinations.
🧭 What Makes It So Different?
Unlike a point-to-point ultra, where distance is finite, a Backyard Ultra strips the sport down to its bare bones:
No advantage for speed — slow and steady survives.
No finish line — only elimination or survival.
No pacing charts — only the next hour matters.
Sleep? Not unless you can nap between loops.
Victory? Only if you’re willing to go one more loop than everyone else.
Every lap is a fresh start — and also a reminder that this race could go on for days.
🏋️♂️ Training for a Backyard Ultra: Different Game, Different Rules
1. 🕒 The Hourly Restart Method
Backyard Ultras demand a special kind of endurance — one where rhythm trumps raw mileage. Here’s how to prepare:
✅ Simulate Hourly Restarts
Start incorporating “loop interval long runs” into your training.
Run for ~45–50 minutes
Rest for 10–15 minutes (walk, refuel, sit, stretch)
Repeat for 4–8 hours
This trains not just your body, but your nervous system to stop and restart effectively — a critical skill on race day.
✅ Night Run Integration 🌙
Run at 1–2 AM occasionally (simulate circadian dips)
Practice waking up to run with 5–10 minutes’ notice
Learn how to layer for temperature swings between night and day
“You’re not just training to run — you’re training to restart over and over again. That’s what breaks people.” — Backyard finisher, 38 loops, 2023
2. 🧱 Build Consistency, Not Speed
Speed won’t save you in a backyard ultra. In fact, going too fast is a trap.
Your goal is to develop a repeatable hourly routine:
Comfortable aerobic pace
Strong form even after 24 hours
No bonks, no spikes — just smooth, even effort
Avoid overdoing speed work. Instead:
Focus on long aerobic efforts
Add strength work for posture (see: [Essential Strength Training Exercises])
Run tired: back-to-back days matter more than weekly mileage
3. 🛏️ Training Fatigue, Not Just Fitness
You’ll likely reach 24+ hours. That means your training must touch the edge of mental and physical fatigue:
Practice long training runs after limited sleep
Learn to function with mental fog
Track your gut tolerance during rest periods
Experiment with 5-10 minute naps during loops (advanced tactic)
Tip: Log every training loop’s time + rest behavior in a Google Sheet to optimize your rhythm over time. (🎁 Bonus tool coming in Part 3!)
🔁 Part 2: Pacing, Hourly Routine & Fueling for the Long Haul
🐢 Slow is Smooth, Smooth is Fast: Pacing in a Backyard Ultra
In a race where there’s no finish line, pacing becomes a paradox: You’re not racing the clock — you’re racing fatigue, boredom, and attrition.
🎯 The Golden Zone: 48–52 Minutes per Loop
You want to complete each loop with:
Enough time to recover (8–12 min)
Not so fast that you spike your heart rate or waste energy
Ideal Range by Runner Type:
🧘♂️ Conservative: 52 min loop, 8 min rest
🎯 Balanced: 49–50 min loop, 10–11 min rest
🔥 Aggressive: 46–48 min loop, 12–14 min rest (risky)
Remember: the rest period is part of the race, not a luxury. Don’t sacrifice rest for extra idle time at the start line.
🔄 Designing the Perfect Hourly Routine
The magic of the backyard ultra lies in your repeatable routine — a sacred cycle of movement, fuel, rest, and reset.
Use a visual checklist near your base setup to ensure you don’t forget tasks when groggy. (We’ll provide one in Part 3 🎁)
📈 Ultra Pacing Insight
Research shows that evenly paced runners perform significantly better than those who alternate fast and slow bursts. Backyard ultra demands metabolic economy and rhythm over speed. Source: Frontiers in Physiology – Ultra Pacing Study
🥤 Nutrition & Hydration: Fueling for the Longest Race
Fueling a backyard ultra is easier logistically, but mentally trickier. Why? Because you have the chance to eat every hour — and that can backfire without a plan.
🍌 Hourly Fuel Guidelines:
Simple carbs every loop: banana halves, rice balls, white bread with honey
Electrolytes every 2–3 loops (tablets, salt caps, or drinks like Tailwind)
Protein/Fat mini-meals every 4–6 hours (instant noodles, nut butter wrap)
⚠️ Avoid big meals too late into the race — digestion slows drastically after 20+ hours.
🔄 Hydration Timing:
Drink during the loop (sip, not chug)
Top off during your rest period
Monitor pee color (yes, still relevant!)
😴 Can You Sleep Between Loops?
Yes, but only if you’re elite-level efficient and practiced.
Some runners master 5–8 minute naps using:
Reclining camp chair or car seat
Earplugs + sleep mask
Alert crew or vibrating alarm
Unless you’ve practiced micro-napping, focus instead on mental resets rather than real sleep early on.
🍽️ Pro Tips from Backyard Vets
💡 “I have a lap rhythm. I know what I eat every 4 hours, when I change socks, and when to switch shoes. I don’t think about the next 30 hours. I just think about the next 50 minutes.” – 2022 Big’s Finalist, 68 loops
💡 “Hot broth at night saved me. Electrolytes and warmth in one. It felt like comfort food.” – Backyard UK, 48 hours
Crew tools: whiteboard with your loop plan, checklist, timer, alarm clock
🧤 Weather Management:
Layers, gloves, beanies for night
Cooling towel, fan for hot conditions
Trash bags for surprise rain storms
🧠 Science Sidebar: Mental vs Physical Fatigue
Studies show mental fatigue reduces endurance performance by up to 15% even when physical capacity remains unchanged. Learning how to mentally “reset” is just as crucial as pacing. Source: Mental Fatigue and Physical Performance
🏁 Notable Race Moments: How Far Can This Go?
The current record? 💀 108 hours. That’s 108 loops. That’s 450+ miles. Held by Phil Gore in 2023 at Dead Cow Gully, Australia.

🇸🇪 Team Backyard World Champs: 15+ countries, relays + solo format
💡 Motivation Box: Why You Should Try a Backyard Ultra 🧠✨
“In a normal race, you’re chasing a goal. In a backyard ultra, you’re discovering your limits.”
You don’t need to be fast — just stubborn.
It’s the purest test of your mind and routine.
You’ll build mental strength like no other race can offer.
The camaraderie is unmatched — everyone cheers, even as they drop.
Try your first one. Run one lap. Then another. You might surprise yourself.
🏊 Cross-Training Strategies for Backyard Ultras
“It’s not about speed — it’s about survival. Build the body that can restart endlessly.”
Backyard Ultra, tekrar tekrar yeniden başlamayı gerektiren, eklem dostu ama uzun süreli yüklenmeye dayanıklı bir vücut ister. İşte bu yüzden cross-training (yardımcı egzersizler), sadece opsiyonel değil — kritik bir hazırlık bileşenidir.
🧱 1. Why Cross-Training Matters in Backyard Ultras
Unlike traditional ultras, you’re not running continuous hours — you’re running, stopping, then starting again, possibly for days. That start-stop stress especially challenges:
Hips and glutes (power source)
Core and spine (postural fatigue)
Feet and calves (shock absorption, balance)
💡 Cross-training helps you build durability without overtraining your running muscles.
🎯 Tip: Combine strength + balance work in one circuit to simulate trail loop fatigue.
🧠 3. How to Integrate It in Your Plan
Day
Session Type
Monday
Rest or Yoga/Mobility
Tuesday
Run Intervals + Core Stability
Wednesday
Strength (Full body) + Light Spin
Thursday
Medium Run or Hike + Stretch
Friday
Strength (Glutes + Core Focus)
Saturday
Long Run (or loop simulation)
Sunday
Recovery Bike or Swim + Foam Roll
Cross-training isn’t just about performance — it’s about injury-proofing your loop engine.
🛌 Tapering & Recovery Runs Before the Race
“You don’t show up to a backyard ultra fit — you show up fresh.”
Tapering isn’t just for marathons. For backyard ultras — where races may last 24, 48, or even 100+ hours — tapering is your best weapon against burnout, fatigue, and mental fog.
📉 1. What Is Tapering?
Tapering is the gradual reduction of training volume and intensity in the final weeks leading up to race day. The goal? 🧠 Recover fully. 🦵 Keep legs sharp. ⚡ Show up mentally and physically ready to restart… every hour.
Important: Taper isn’t about doing nothing. It’s about doing less, but purposefully.
🧘 3. Recovery Run Tactics
Use these as reset tools, not as performance boosters.
🎯 Purpose:
Flush lactic acid
Boost circulation
Mentally reconnect with movement
⏱️ Format:
20–40 minutes max
Conversation pace
Trail or flat dirt road preferred
🔄 4. Mental & Physical Reset Week
Final 5 days before race:
🧘 Light yoga or meditation every morning
🛀 Magnesium baths or contrast showers
🎧 Listen to previous race stories or your own race plan
📓 Review gear checklist (more on this in upcoming section)
💡 Your goal is not to sharpen the blade — it’s to keep it from dulling before the real test begins.
🌘 Managing Hallucinations and Sleep Deprivation
“When the race gets weird, get weirder — but stay on the loop.”
After 24, 36, or 48 hours of running with only a few minutes’ rest each hour, your brain starts to fray. Hallucinations, confusion, emotional swings, and microsleeps become not rare — but expected.
👁️🗨️ 1. Why Hallucinations Happen
Sleep debt: Skipping full REM cycles
Glucose depletion: Brain runs on low fuel
Loop fatigue: Repetitive terrain dulls awareness
Circadian misalignment: Running at 2–4 AM hits your biological shutdown point
🧠 Your brain starts filling in visual gaps with fantasy to make sense of the monotony.
👻 2. Real Hallucinations from Real Backyard Ultras
“I saw a man in a suit in the bushes waving at me. He vanished when I waved back.” — Runner, 2021 Backyard UK
“The trail looked like it was floating. I stepped ‘up’ onto it and almost fell.” — 72-hour runner, U.S. qualifier
“I kept thinking my crew was standing beside me, but I was alone.” — 30+ loop finisher
Use a light that flickers slightly — mimics motion better
Switch headlamp position (head vs chest)
😴 4. Dealing with Sleep Deprivation
Microsleeps (1–10 seconds of blackout) can occur during night loops.
💡 Tips:
Consider scheduled standing naps (~5 min) at loop 30+
Use crew to shake you gently if you drift at camp
Avoid sitting too comfortably if you’re prone to nodding off
🧠 Caffeine is your ally — but time it carefully (avoid caffeine crash around dawn).
🧠 Science Sidebar: Why Do You Hallucinate During Ultras?
According to sleep researchers, total sleep deprivation beyond 36 hours can trigger visual and auditory hallucinations, mood swings, and impaired decision-making — common in backyard ultras. Source: Sleep Deprivation and Hallucinations, NIH
💡 Bonus Hack: Alertness Shots
Try cold-pressed ginger + lemon shots
Or drink broth + espresso combo
Use every 3–4 hours to reset internal rhythm
“The hallucinations don’t stop you — they just remind you that this is now a mental race.”
👥 Crew vs Solo: How to Structure Your Support Team
“In a Backyard Ultra, your crew is your pit crew. Every second counts — and every word matters.”
Backyard Ultras test your ability to start again and again. But who helps you restart?
Some runners go solo — handling every loop, snack, and reset alone. Others bring dedicated crews who act like NASCAR pit teams. Both strategies work… if you know how to use them.
🧍 Going Solo: Can You Survive Alone?
✅ Advantages:
Fewer distractions
Total control over gear & nutrition
More minimalist, self-reliant setup
❌ Disadvantages:
No one to warn you about time
Mental isolation can break you
Harder to manage gear, food, and timing
💡 Tip: Solo runners should build a “visual basecamp checklist” and set loud alarms for 59:30 minutes.
🥤 Nutrition Note: Why Small, Frequent Meals Matter
Gastrointestinal distress is the leading reason ultrarunners drop out. The gut absorbs nutrients better in small doses under stress. Hourly fueling reduces risk of nausea and cramping. Source: iRunFar: Fueling Long Ultras
🤝 Racing with a Crew: Division of Survival
A well-trained crew can:
Prepare food between loops
Handle gear, shoes, clothes
Set up alarms and wake-up calls
Give motivational cues when your mind fails
Notice injuries or signs of breakdown
🧑🍳 Suggested Roles in a 1–3 Person Crew:
Crew Role
Responsibilities
Captain
Timing, wake-ups, countdowns
Fuel Chief
Prepares hourly food, hydration
Gear Manager
Handles socks, shoes, lights, repairs
Motivator
Keeps spirits high, monitors morale
A solo runner needs to think for themselves. A good crew makes sure the runner doesn’t have to.
⏱️ Loop Routine with a Crew (Sample):
45–48 min: Finish loop
48–50 min: Sit, towel off, get brief status update
💡 The key to crewing isn’t doing everything — it’s creating calm so the runner only needs to move and survive.
👨👩👧👦 What If You’re Using a Partner or Friend?
Even 1 person can act as a powerful crew. Train them in advance:
How to speak during fatigue (clear, short, supportive)
When to offer food vs stay quiet
How to handle runner resistance (“I don’t want to eat.” → “One bite.”)
🏕️ Crew Setup Essentials:
Chair + headlamp for each crew member
Pre-labeled bags for gear changes
Printed schedule of nutrition and routine
Duct tape, scissors, body wipes, electrolyte mix
Shared mantra or motivational phrases
🧾 Quick Checklist: Your Hourly Loop Survival Kit
“One missed sock change can end a 40-hour run. Checklist = survival.”
In a backyard ultra, success lives in the small details. Having your gear, fuel, and recovery systems organized per loop prevents decision fatigue and critical errors as the hours pile on.
Below is your master checklist for basecamp setup, hourly routine, foot care, and mental prep.
🏕️ Basecamp Essentials
☐ Chair (reclining if possible)
☐ Tent or canopy (weather protection)
☐ Table or crate for gear organization
☐ Headlamps (x2) + spare batteries
☐ Portable clock or alarm system
☐ Cool box or hot food thermos
👟 Gear & Foot Care
☐ 2–3 pairs of running shoes (alternate hourly or every 6 loops)
