Race Library
Creating a race plan for a technical trail race or ultra marathon is important but can be quite tricky.
Routes through tough environments with lots of elevation gain make it difficult to predict what pace you'll be able to run.
This tool will help you create your own pace chart so you can race smart, finish safely and reach your running goals.
This tool will allow you to come up with your own race plan and help answer questions like...
- How fast should I start the race in order to have a chance to finish in the top ten?
- My goal is a sub 24h finish. How should I pace myself?
- When should my crew expect me to arrive at this aid station?
- I'm a spectator and want to make sure I don't miss the leaders. When should I be at the finish line?

Warning!
The tools on this website can help you plan your race but you should never solely rely on them in order to finish safely.
Weather conditions and personal form on race day are unpredictable and can affect your running-pace dramatically.
The predictions are based on data from previous years. Race courses and aid stations might vary.
Always check the official information provided by race directors.
