🏃‍♂️ What Is an Ultramarathon, Anyway?

It’s not just “longer than a marathon” (but also yeah, kinda)

Ultramarathons are the Wild West of running. 🤠 No one’s really in charge, the distances are kinda made up, and the rules? Loose at best. But if there’s one thing that does define an ultra, it’s this:

It’s longer than a marathon.

That means anything over 26.2 miles earns the “ultra” label — but that’s just the entry point.

Because here’s the truth: once you step into the ultra world, you’re not just running longer. You’re stepping into a different sport entirely. 🧭

📏 How Long Are Ultramarathons, Really?

The shortest standard ultra is a 50K — roughly 31 miles — and that’s where a lot of folks dip their toes in. 🦶 But the deeper you go, the weirder (and more impressive) it gets.

Here’s a breakdown of common ultra distances:

• 🥾 50K (31 miles): The “starter ultra.” A popular jump from road marathons into trails.

• 🔥 50 Mile: Where things get spicy. Usually a full-day effort.

• 🌘 100K (62 miles): Two marathons, back-to-back. Night running often included.

• 🧠 100 Mile: The crown jewel. Sleep-deprivation, hallucinations, and emotional spirals included.

• ⛺ 200+ Miles: Multi-day epics through mountains, deserts, and self-doubt. (Looking at you, Cocodona.)

🏞 Road vs. Trail Ultras

Most ultras ditch the pavement and head straight into the dirt. 🪵

That’s because ultra distances are brutal on the body, and running 50+ miles on asphalt? That’s a recipe for disaster. Trails, with their softer terrain and varied scenery, are easier on joints and harder on your soul — in the best way.

But road ultras do exist. The 🏛 Spartathlon, 🔥 Badwater 135, and 🇿🇦 Comrades Marathon in South Africa all stick to pavement and attract serious talent.

Still, if you’re picturing mud, singletrack, elevation, and the occasional mountain goat 🐐 — you’re in the right ballpark.

🧠 Why Do People Run These?

Because… why not?

Ultras attract a certain breed of runner — the kind who looks at a 26.2-mile race and thinks, “What if we kept going?” 🌀

It’s not just about distance. It’s about pushing your limits, solving problems on the fly, and testing how far your body (and mind) can really go. You’ll run through the night 🌌, fight stomach issues 🤢, deal with blisters the size of silver dollars 🫣, and maybe cry a little 😅.

But you’ll also see sunrises you’ll never forget 🌄, meet people who genuinely get it 🤝, and cross finish lines that feel like miracles 🎉.

🎒 What Gear Do You Need?

Ultrarunning isn’t cheap, but you don’t need to spend a fortune to start. Here’s what you do need:

• 👟 Trail shoes (if it’s not on roads)

• 💧 A hydration vest or handheld bottles

• 🍌 Nutrition you’ve tested on long runs

• 🔦 A headlamp (trust us)

• 💪 Guts and grit (non-returnable)

As you get deeper into the sport, you’ll pick up more — trekking poles, gaiters, salt tabs, maybe even a crew. But for your first 50K? Keep it simple.

🤔 Is Ultramarathoning for You?

If you’ve ever finished a marathon and thought, “I’m not done yet,” you might be an ultrarunner at heart. ❤️‍🔥

You don’t need to be fast. You don’t need to be a pro. But if you’ve got patience, stubbornness, and a weird desire to suffer in beautiful places, ultras are calling. 📞

Whether it’s a 50K through rolling forest trails or a 100-miler across remote mountain passes, the ultramarathon world is wide open — and totally worth exploring.
