How to Choose Your First Ultra Marathon
Published 2025-02-10
Picking the right first ultra is almost as important as training for it. A brutal mountain 50K with 10,000 feet of climbing is a very different experience from a flat trail loop.
What to Look For
Looped courses: Multiple loops mean you pass through the start/finish area several times. This gives you access to your gear, your crew, and a mental boost.
Moderate elevation: Under 3,000 feet of total climbing for your first 50K. Save the mountain races for later.
Good aid stations: Look for races with aid stations every 4-6 miles. More support = less you need to carry.
Generous cutoffs: A 10+ hour cutoff for a 50K gives you breathing room. Don't pick a race where you'll be stressed about time.
Red Flags for a First Ultra
- "Technical terrain" in the description
- Mandatory gear lists longer than 10 items
- Elevation profiles that look like an EKG
- Cutoff times under 8 hours
Our Recommendation
Start with a local 50K on runnable trails. Ask in local running groups — experienced ultra runners love recommending races to beginners.
