Have you run a marathon but don't know how to step up to an ultramarathon?
Get matched with a qualified coach who understands your race, your current running experience and everything your first ultra adds, from fuelling and climbing to cut-offs and hours on tired legs.

Your first ultra isn't difficult because it's longer. It's difficult because there are more ways for your race to go wrong
| Race | DNF rate |
|---|---|
| Black Beacon 100 Mile | 55% |
| Devon Coast to Coast | 50% |
| Pilgrims Ultra - 100km | 36% |
| Ultra Trail Snowdonia 50km | 19% |
| Arc of Attrition 50 Mile | 17% |
| Average Marathon | ~2% |
Your first ultra isn't difficult because it's longer. It's difficult because there are more ways for your race to go wrong
Most marathoners stepping up to an ultra do not need convincing that they can run. They have already trained for 26.2 miles and finished it.
The difference is that an ultra introduces problems a marathon may never have forced you to solve: prolonged fatigue, hours of bad weather, technical terrain, eating while running for most of a day, intermediate cut-offs, and keeping your effort under control when there is still a very long way to go.
What coaching actually changes
Knowing an ultra is hard doesn't help you finish one. Here is what a coach does about each of the problems that end first ultras early.
| The problem | What the coach actually does |
|---|---|
| 23% cited injury | Builds volume progressively around your history, adjusts training when niggles appear and avoids blindly following a fixed plan. |
| 20% debilitating fatigue | Teaches effort management, hiking/running strategy and how to train effectively on tired legs. |
| 17% performance/cut-offs | Builds pacing around your actual race's climbs, terrain, aid stations and cut-offs. |
| Fuelling | Helps you develop and repeatedly test a fuelling strategy during training. |
| 38% weather | Prepares you for your race environment, kit requirements and contingency scenarios. |
Why Ultrarunners DNF
A 2025 study of runners looked at why runners withdrew from long-distance mountain races. Among those who dropped out, these were the most commonly reported reasons.

More hours out there changes what your body needs
A marathon is raced at pace and over in a few hours. An ultra is survived over time, sometimes the best part of a day or more, and that extra time is exactly what turns effort management and fuelling into their own training problems.
Time on feet by distance
| Distance | Time on feet |
|---|---|
| Marathon | ~4 hrs |
| 50km | ~5-7 hrs |
| 50 mile | ~9-14 hrs |
| 100km | ~12-18 hrs |
| 100 mile | ~24-36 hrs |

You don't need someone to tell you that ultras are hard
You need someone who can look at the race you are entering, where your fitness is now, the time you have available, and the experience you already have, then work out what actually needs to change.
The right coach helps turn "I think I can run this" into a preparation process built around the race you actually have to finish.
There's a coach for everyone
Every coach on the platform is qualified, accredited, and insured, but they are not interchangeable. Some made their own jump from marathon to ultra later in life, some around a full-time job and young kids, some on trails, others on the road. You are matched with the one whose own experience lines up with yours, not just whoever has a free slot.
Your race
Terrain, climbing, climate, cut-offs, and self-sufficiency demands, mapped out and matched to coaches who have faced them.
Your goals and preferences
Finishing safely and racing for a place need different coaches. So do the athletes who want structure and the ones who want flexibility.
Your schedule
The hours you can train, the days that work, holidays and travel. Your plan is built around your life, not an ideal week.
