New Ultramarathon Races in 2025 🏃 – 5 Debuts You’ll Want on Your Calendar

🧭 Introduction: The Rise of New Ultramarathons

In the world of ultrarunning, there’s a quiet revolution underway.

Every year, new races emerge—some in far-flung jungles, others in sleepy mountain towns or sun-scorched deserts. They begin as whispers, perhaps a trail runner’s dream scribbled in a notebook, or a wild idea passed over coffee by a local running club. And before you know it, they become real: marked trails, cutoff times, aid stations with peanut butter sandwiches, and a starting line waiting to be crossed.

In 2025, that revolution is gaining serious momentum.

💡 According to race listing sites and the ever-expanding UTMB World Series calendar, more new ultramarathon events are launching this year than ever before. We’re not just talking about small community fun runs. We’re talking about fully-fledged, timed, marked, legit ultras—some pushing into 100-mile or even 200+ mile territory.

But why is this happening?

There are a few good reasons:

• Demand is exploding. Trail and ultra participation has grown steadily post-pandemic as more runners seek adventure, solitude, and something raw.
• The world is connected. With tools like Strava, RaceID, and social media, it’s easier than ever for local race directors to reach a global audience.
• Ultras are becoming… cooler. Once niche and fringe, ultrarunning is now a badge of honor for a new breed of endurance athlete. It’s where the misfits, adventurers, and dreamers gather.

More importantly, new races offer something iconic events often can’t:
🏁 A blank page.

You’re not just signing up for a race—you’re signing up to be part of something from the very beginning. There are no legacy finishers, no 20-year veterans. Just you, the trail, and a bunch of equally curious runners toeing the start line of the unknown.

And that’s powerful.

Because maybe, just maybe, 20 years from now someone will say,
“Wait—you ran the very first edition of that race?”

🎯 What This Guide Offers

In this post, we’ll spotlight five brand-new ultramarathon races set to debut in 2025. These events span continents and climates, from rainforest loops to desert crossings. For each, we’ll explore:

• 📍 Where it is and what makes it unique
• 🛠️ What kind of runner it’s suited for
• 🔥 Why you might want to sign up for the first edition

And, as a personal touch, I’ll share a bonus pick from my own backyard: the majestic Kaçkar Mountains, home to a brand-new UTMB event that’s as wild as it is wonderful.

---

📌 Motivation Box:

“The first edition of a race is always the most raw, most real. You become part of its DNA.”

So, are you ready to discover the trails of tomorrow?

Let’s dive into the fresh, bold, and uncharted world of new ultramarathons in 2025.

🌍 Mapping the New Frontier: Where the 2025 Races Are

One of the most exciting things about ultrarunning in 2025 isn’t just the increase in new races—it’s where they’re happening.

These aren’t your standard courses in California or the Alps (although we love those too). No, the newest ultras are pushing boundaries, both literally and figuratively. They’re popping up in unexpected regions—remote jungles, forgotten deserts, glacial valleys, and coastal cliff trails that have barely seen a pair of trail shoes.

Let’s zoom out and take a look at the global map of new ultramarathons debuting in 2025.

---

🗺️ A Global Spread of Grit

🌎 Continent	🏃 Race Name	📍 Location
North America	The Freedom 50, Cocodona 250	Washington, Arizona (USA)
Asia	Amazean Jungle Thailand by UTMB	Betong, Thailand
Oceania	Ultra-Trail Australia 100-Miler	Blue Mountains, Australia
Europe	Trans Europe Foot Race	Germany to San Marino
Middle East / Eurasia (Bonus)	Kaçkar by UTMB (Bonus Pick)	Kaçkar Mountains, Turkey

---

🌐 What This Tells Us About Ultramarathon Culture

This global distribution isn’t random—it reflects the evolution of ultrarunning as a cultural force. Once confined to niche pockets in the U.S. and Western Europe, ultramarathons are now becoming:

• 🏞️ Vehicles of adventure tourism (especially in Asia and Latin America)
• 🌱 Eco-conscious events held in national parks and wilderness zones
• 🧭 Cultural exchanges, where local traditions meet global endurance communities

In short: ultramarathons are no longer just races. They’re passports to the planet.

---

✨ Why This Matters for Runners

Choosing a new race isn’t just about the distance—it’s about the experience.
Are you looking for:

• ❄️ A snowy alpine challenge?
• 🌴 A tropical, steamy, all-senses jungle grind?
• ☀️ A multi-day, sunburned desert pilgrimage?

These 2025 events offer a spectrum of conditions, climates, and cultures—so you can pick a challenge that fits your story.

---

📌 Runner Tip:

Don’t just search for “the best race.” Search for the race that speaks to your soul. The one that scares you a little—and excites you a lot.

🧠 What Makes a Debut Ultramarathon Worth It?

Let’s be honest—signing up for a first-year ultramarathon can feel like a gamble.

There are no race reports. No detailed YouTube recaps. No Strava segments to analyze. You might not even find a single blog post about it (yet). So why do some runners chase these inaugural races with more fire than a golden ticket to Western States?

Because there’s something undeniably special about being first.

---

🚩 The Allure of Running Something New

Running a debut ultramarathon is like discovering a trail before it’s on the map. You don’t know exactly what’s ahead—and that’s the point.

Here’s what draws trailblazers to first-edition events:

• Be part of history. You’ll forever be in the results list of the very first edition. Years later, when the race is famous, you can say, “I was there before it was cool.”
• Raw and real experience. New races are often more intimate, less commercial, and more connected to the local community. You’re not just a bib number—you’re part of the foundation.
• Less competition, more connection. Smaller field sizes mean stronger bonds with fellow runners and a better chance at podium finishes or top placements.
• Potential for softer cutoffs. Organizers often allow extra buffer time in the first year, accommodating unexpected challenges for both runners and crew.

---

🧪 The Risk Factor

Of course, there’s a flip side to the charm.

New races come with quirks:

• Unproven logistics
• Sparse aid stations
• Poor course markings (sometimes)
• Lack of crowd support or fanfare

But here’s the thing—most experienced ultrarunners know this going in. They plan accordingly. And for many, that adds to the appeal.

After all, isn’t that what ultrarunning is all about? Adapting. Overcoming. Embracing the unknown.

---

📋 The First-Timer’s Checklist: Choosing the Right Debut Ultra

If you’re tempted to sign up for a 2025 debut race, here’s what to evaluate before you commit:

✅ Factor	Why It Matters
Organizer’s reputation	Have they directed other races? Do they partner with trusted names (e.g., UTMB, Aravaipa)?
Course profile	Is the terrain technical? Are elevation gain/loss details clear?
Aid station spacing	How often can you refuel? New races may have minimal support.
Weather expectations	First-time events may be held in unpredictable seasons.
Refund/reschedule policy	Especially important for international travel or uncertain regions.
Runner cap and field size	Smaller events can be more personal—but less forgiving logistically.

---

🧭 Bottom Line:

New ultras are for the curious, the bold, and the ready-to-adapt.

You’re not just racing the miles—you’re helping shape the story of a race that might become legendary one day.
That’s the difference between being a runner… and a pioneer.

---

📌 Motivation Box:

“Known terrain can make you faster. Unknown terrain can make you stronger.”

🏃‍♂️ Race #1: The Freedom 50 (Washington, USA)

Imagine standing at a quiet trailhead in the Pacific Northwest, mist rising from dense conifers, a soft chill in the air. It’s Memorial Day weekend, and while others are lighting grills, you’re lacing up trail shoes, preparing to toe the line for the very first edition of The Freedom 50.

There are no previous champions. No course records. Just trail, potential, and you.

Welcome to The Freedom 50—a brand-new ultramarathon launching in May 2025 that blends the rugged charm of Washington State with the raw energy of first-time events.

---

📍 Race Snapshot:

Detail	Info
Location	Puyallup, Washington (USA)
Distance	50 miles (80.4 km)
Date	May 24–25, 2025 (Memorial Day Weekend)
Elevation	~7,000 ft gain (2,134 m)
Cutoff	14 hours
Participants	Capped at 150 runners
Organizer	Local trail running collective, new series

---

🌲 The Vibe: Local, Lush, and Looped

Set in the shadow of Mount Rainier, The Freedom 50 is designed with simplicity and beauty in mind. The course features two large loops through forest singletrack, stream crossings, soft pine-covered climbs, and smooth fire road descents.

There are three main aid stations, placed roughly every 10 miles, with an optional drop bag location at mile 25. Expect a humble setup—PB&Js, potatoes, Tailwind, and smiling volunteers—but don’t expect flashy banners or drone coverage. This is about grit, not glitz.

What makes this race especially appealing is the combination of:

• Moderate terrain (ideal for first-time 50-milers)
• Gentle elevation profile
• Early summer weather (cool mornings, mild afternoons)

---

🎯 Who Should Run It?

This is a race built for:

• Runners transitioning from marathon or 50K distances
• Locals looking for a quiet but meaningful ultra experience
• Anyone who wants to run a debut event without extreme logistics or technical risk

It’s also a great race for friends. The looped course allows for overlapping paces and frequent crewing.

---

✨ Why It Could Become a Future Classic

If the weather holds and the trails run clean, The Freedom 50 has everything a regional ultra needs to grow:

• Stunning setting
• Low-stress logistics
• Friendly volunteer culture
• A date that fits well in the training calendar

In 3–5 years, don’t be surprised if this becomes a sought-after West Coast spring ultra. And you’ll be able to say: “I ran the very first one.”

---

📌 Runner Persona:

“First-timer chasing a finish.”
Whether you’re upgrading from your first 50K or coming back from injury, this course offers forgiveness and finish-line confidence.

🌴 Race #2: Amazean Jungle Thailand by UTMB (Betong, Thailand)

Some ultras test your legs. Others test your lungs. But every now and then, you find a race that tests every sense at once.
Welcome to the Amazean Jungle Thailand by UTMB, debuting in May 2025, where the terrain is thick, the air is heavy, and the experience is unforgettable.

If you’ve ever dreamed of running through steamy rainforest trails, surrounded by ancient trees, jungle calls, and humidity so thick it clings to your soul—this is your invitation.

---

📍 Race Snapshot:

Detail	Info
Location	Betong, Yala Province, Southern Thailand
Distances	20K, 50K, 100K, 100 Miles
Elevation	100M: ~4,500m gain / 100Mile: ~6,000m
Cutoffs	100K: 24h / 100M: 38h
Organizer	UTMB World Series (first Thai edition)
Event Dates	May 1–4, 2025

---

🌴 The Setting: Raw, Tropical, and Wildly Underrated

The race takes place deep in the Betong region of Southern Thailand—an area known for its remote jungle landscapes and cross-border cultural mix. Until now, this region was largely unknown to international runners.

Expect:

• Narrow jungle singletrack
• Slippery, moss-covered stones
• Rope sections on climbs
• River crossings
• Humid, monsoon-style conditions

This is not your average runnable ultra. It’s a wet, lush, survival-meets-suffering type of trail, and that’s exactly what makes it special.

---

🔥 Why It Stands Out

Thailand has hosted ultras before (The North Face 100, UTMB Doi Inthanon), but Amazean Jungle is different:

• It’s more remote than any other UTMB Asia race
• The climate is extremely demanding—think 90% humidity at midnight
• It’s a cultural gateway: remote temples, bamboo huts, Malay-Thai border villages

Plus, as a UTMB World Series event, finishers can earn Running Stones toward Mont Blanc entries—adding serious prestige for those chasing UTMB qualification.

---

🧭 Who Should Run It?

This race is built for:

• Experienced trail runners who love suffering with style
• Climbers and jungle veterans
• UTMB collectors seeking Stones in exotic terrain
• Runners who’ve done Alps or Rockies and want to test a whole new kind of challenge

📌 Pro Tip: Bring poles, extra socks, and serious electrolyte management. You’ll sweat out your bodyweight twice over.

---

🎯 Will It Last?

Amazean has UTMB backing, beautiful terrain, and a uniqueness factor that can’t be replicated in Europe or North America. It may never attract thousands—but it doesn’t need to.

It only needs a few hundred gritty runners each year who crave something beyond elevation and pace.

---

📌 Runner Persona:

“The humidity-hardened explorer.”
This is for those who don’t flinch at mud, rope climbs, or leeches—and prefer the sound of monkeys over music at aid stations.

🏔️ Race #3: Ultra-Trail Australia 100-Miler (Blue Mountains, Australia)

For years, Ultra-Trail Australia (UTA) has been one of the Southern Hemisphere’s most celebrated trail events—renowned for its stunning scenery, enthusiastic crowd support, and a tough-but-accessible 100K race format.
But in 2025, it’s taking things up a notch.

For the first time ever, UTA is adding a 100-Mile option, transforming an already iconic event into a true test of endurance—and inviting runners from around the world to write history on brand new ground.

---

📍 Race Snapshot:

Detail	Info
Location	Katoomba, Blue Mountains, NSW, Australia
Distance	100 Miles (160.9 km)
Elevation	~7,500 m gain (24,600 ft)
Date	May 16–17, 2025
Cutoff	38 hours
Organizer	Ironman Group / UTMB World Series
Field Size	Limited entry (first edition)

---

🏞️ The Course: Old Roots, New Horizons

While the 100K and 50K versions of UTA have carved out legendary status in the trail world, the 100-Mile edition debuts in 2025 with a dramatic expansion of the course.

Expect:

• Brand-new singletrack sections
• Steeper ascents through narrow canyons
• More isolated nighttime stretches
• Extended loops deep into Megalong Valley and remote wilderness zones
• The return of the infamous stairs—but now, at mile 85…

It’s not just a longer version of the 100K. It’s an evolution.

---

✨ Why This Race Matters

The Ultra-Trail Australia 100-Miler instantly becomes one of the toughest milers in the UTMB World Series, both for its terrain and climate.

What makes it exciting:

• It brings a 100-miler to an already proven festival atmosphere
• It’s logistically easier than many alpine ultras (no high-altitude acclimatization needed)
• The weather is unpredictable—rain, wind, even hail are all possible in May

And for Australians (or those in the Asia-Pacific region), it provides a UTMB qualifier without crossing continents.

---

🎯 Who Should Run It?

This is an ideal race for:

• UTA 100K veterans looking for the next challenge
• European or North American runners seeking a “destination ultra” without major altitude
• Mid-to-back-packers who want to test themselves over 38 hours of well-supported wilderness
• Hardcore stair-lovers (you know who you are)

📌 Pro Tip: If you’ve run the 100K before and thought “this is hard but I want more”—congratulations. The 100-Mile version heard you.

---

🌟 First-Year Buzz

Registration sold out in hours.
The hype is real.
Social media is already buzzing with finish line predictions, crew strategies, and gear debates.

UTA100M will likely become Australia’s premier 100-mile trail event—and 2025 is your only chance to be part of the origin story.

---

📌 Runner Persona:

“The experienced grinder ready to go longer.”
You’ve tackled 50s and 100Ks. You want a legit miler with deep community vibes and sharp technical tests. You’re also okay with thousands of stairs.

🔥 Race #4: Cocodona 250 (Arizona, USA)

Some races are long.
Some races are hard.
And then there’s Cocodona 250—a race so wild, so vast, and so absurdly demanding, it borders on the mythical.

Technically not a first-year event (its inaugural year was 2021), Cocodona 250 earns a place in this 2025 guide because it continues to reinvent itself with new route segments and evolving challenges—and for many runners, 2025 will be their first encounter with this beast.
Plus, no discussion of new-era ultras is complete without it.

---

📍 Race Snapshot:

Detail	Info
Location	Arizona, USA
Distance	250 miles (402 km)
Elevation Gain	~12,000 m (39,000 ft)
Cutoff Time	125 hours (5 days + 5 hours)
Start	Black Canyon City
Finish	Flagstaff
Date (2025)	May 5–10, 2025
Organizer	Aravaipa Running

---

🌵 The Terrain: Grit, Heat, and Altitude

Cocodona isn’t just a race—it’s a five-day psychological expedition across one of America’s harshest and most beautiful landscapes.

You’ll climb out of desert basins, scramble over rocks and boulders, pass through sleepy towns, endure searing daytime temps, and shiver during cold high-altitude nights. The course links together a cross-section of Arizona’s topography like no other race on earth.

Sections include:

• 🔥 The brutal heat of the Sonoran Desert
• 🌲 The cool pines of the Coconino Plateau
• 🏔️ The monster climb up Mingus Mountain
• 🏙️ Historic mining towns and remote trail systems
• 😵 “Hallucination Alley” (yes, it has a name…)

---

🎯 Who Should Even Attempt This?

Cocodona is not for everyone. It’s built for:

• Runners with 100+ mile experience and then some
• People who are mentally tough enough to function on <2 hours of sleep
• Athletes who love spreadsheets, gear dial-ins, and sleep-deprivation as a sport
• Trail dreamers who want to push past their known limits and see what’s left

📌 Warning: If you hate sand, climbing, or not showering for four days—run the Freedom 50 instead.

---

💥 What’s New in 2025?

• Improved town segment integration (more historic towns, more aid stations with real food!)
• Optional “sleep zone” tents at key points for longer rests
• New live tracking and media coverage features
• Rumors of a time-based Cocodona leaderboard (e.g., 3-day finishers = special badge)

In short: Cocodona is not resting on its already brutal reputation—it’s expanding, evolving, and doubling down on the extreme.

---

🏅 Why It’s Legendary Material

Finishing Cocodona grants you more than a buckle—it gives you a badge of madness, proof that your limits are deeper than you ever imagined.

This isn’t a race people sign up for lightly. And that’s what makes it iconic.

📌 Bonus: Aravaipa’s race culture is elite—expect thoughtful aid, wild media content, and a crew of volunteers that live for ultra insanity.

---

📌 Runner Persona:

“The ultra-sufferfest connoisseur.”
You’ve done the 100s. Maybe even a few 200s. Now you want something raw, long, underhyped, and legendary. You don’t fear hallucinations. You embrace them.

🏔️ Bonus Pick: Kaçkar by UTMB (Rize, Turkey)

Some races you choose.
Some races choose you.

Hidden in the far northeast of Turkey, rising above clouds and tea fields, the Kaçkar Mountains form one of the wildest, most mysterious landscapes in the UTMB World Series. And in 2025, these jagged giants will roar to life as a debut ultra on the global calendar.

This one’s personal.
Because I live here.
And I can promise you: Kaçkar isn’t just a race—it’s a pilgrimage.

---

📍 Race Snapshot:

Detail	Info
Location	Rize, Turkey – Kaçkar Dağları
Distances	20K, 50K, 100K, 100 Miles
Elevation Gain	100K: ~5,000m / 100M: ~8,000m+
Event Date	Likely August or September 2025 (TBC)
Organizer	UTMB World Series + Local Trail Partners
Unique Feature	Remote high-alpine meadows, glacial lakes, shepherd trails, and storm-sculpted ridgelines

---

🏞️ The Experience: Wild, Weathered, and Wholly Unfiltered

Kaçkar is not a “just show up and run” type of race.
It demands respect—from your lungs, your gear, and your soul.

You’ll ascend through:

• Dense Black Sea forest
• Misty alpine pastures (yaylas)
• Rocky ridgelines with thunderclouds looming
• Ancient herding paths carved through stone and fog
• Glacial lakes reflecting nothing but silence

The air here is thin. The weather is moody. The mountains are alive.

---

🌬️ Why This Race Matters

Kaçkar by UTMB represents a rare confluence:

• A newly globalized race in a culturally rich, untouched region
• One of the first World Series races in Eurasia’s wildest alpine zones
• A chance to bring local runners into the international spotlight

And more than that: it’s not a polished jewel.
It’s a raw gem still partly buried in the earth.
You’ll help shape it with your footprints.

---

🤝 Local’s View: What You Need to Know

I’ve walked these trails. I’ve sat with shepherds over tea on the same ridges you’ll race across. I’ve seen the sun rise behind glacier peaks, and I’ve been caught in fog so thick I couldn’t see my shoes.

If you join this race, you’re not just visiting Kaçkar.
You’re meeting it.

📌 Tips from the inside:

• Bring rain protection—weather changes in minutes
• Poles are essential.
• Respect altitude. Some passes reach ~3,300m
• Allow a few days pre-race to acclimate and absorb the quiet

---

📌 Runner Persona:

“The soul chaser.”
You run for the silence. For the unknown. For places that don’t care how fast you are. You seek altitude, authenticity, and a race that whispers instead of shouts.

🏁 Conclusion: Trailblazers Wanted

In a sport already defined by unpredictability and challenge, there’s something uniquely bold about choosing to run a race that’s never been run before.

These five races—plus the wild Kaçkar bonus—aren’t just new dots on the calendar. They’re stories waiting to be written.
And if you’re reading this, maybe you’re one of the people who’s meant to write them.

Because running a new ultramarathon isn’t about a shiny medal or a perfect course.
It’s about stepping onto trails no one has raced yet, where every root and ridge is unexplored racing ground.
It’s about trusting your preparation when no finish-time benchmark exists.
It’s about saying yes to a challenge that comes with no guarantee… only the promise of something unforgettable.

---

🔥 Why You Should Pick One of These New Races in 2025

• 🛤️ Escape the crowd. Big-name races are fun—but so are quiet start lines and open trail.
• 🌎 See the world. These events span continents and cultures. You can run in fog-covered forests or furnace-hot deserts.
• 🧠 Test your grit. With fewer race reports and less predictability, your adaptability becomes your superpower.
• 📜 Be remembered. There’s only one first edition. And only a few people will ever say, “I was there when it all began.”

---

📌 Your Move

Whether you’re chasing your first 50K or your fourth 200-miler…
Whether you crave wild landscapes, epic logistics, or just a good story to tell…
There’s a race on this list for you.

So here’s your nudge:
Choose the one that excites you.
Choose the one that scares you a little.
Choose the one no one’s finished yet.

❓ Frequently Asked Questions About New Ultramarathon Races

🌍 Are new ultramarathon races reliable?

While newer races may lack history, many are backed by experienced organizers (like UTMB or Aravaipa) and offer excellent structure. Check the official race site, past event experience of the organizers, and community feedback.

🧭 How do I choose the right debut ultra for me?

Consider your experience level, preferred terrain (mountain, desert, jungle), climate tolerance, travel capacity, and whether you want a festival vibe or a raw wilderness challenge. Our quiz at the end of this article can help!

🥾 Do I need special gear for new or remote races?

Yes. Plan for self-sufficiency: bring trekking poles, hydration packs, emergency nutrition, and weatherproof gear. For long or untested routes, consider carrying a GPX file and portable charger for navigation.

📆 What if a new race gets canceled or changed?

Always read the cancellation/reschedule policy before signing up. Some newer races offer partial refunds or deferment. Booking travel and lodging with flexible options is a smart move.

🧠 Are new races harder mentally?

Often, yes. Without detailed race reports or local beta, you rely more on adaptability, intuition, and resilience. Treat it like an expedition: embrace the unknown, and you’ll emerge tougher.

🏔️ Should I train differently for a first-year ultra?

Yes. Focus on preparing for longer aid gaps, route-finding, variable weather, and slower terrain. Back-to-back long runs and mental resets are crucial. Check our back-to-back long run guide for tips.
