As part of your exploration of the legendary race that is the UTMB®, it's time to look at the courses on offer to competitors, understand the differences between them, and get to grips with the key race rules. The route, GPX file, course profile and aid station locations can all be found on the official race website.

Race distances
The UTMB® organisation runs many races — not just the "original UTMB®". Shorter distances are available to suit all levels and to welcome those who aren't ready to tackle the 174-kilometre main course. In total, 7 different races are on offer, giving everyone the chance to find their challenge!
Time limits
For most of these races, the organisation sets a time limit to complete the distance. This is the maximum time allowed — stay within it and you qualify as a finisher of the race you chose to enter.
Cut-off times
In addition to maximum time limits, there are cut-off times for each race. These are the maximum times after which you can no longer leave a checkpoint. If you leave a checkpoint after the cut-off time, you will be disqualified. These cut-off times have been put in place for safety reasons and to avoid keeping all the infrastructure and organisation staff in place for too long.
Aid stations
Fortunately, the organisation has also set up aid stations. Knowing them is essential — they are an integral part of your course knowledge and help you manage your nutrition effectively. They come in several types (liquids only, solids + liquids, hot meals) and are spaced at roughly regular intervals along the route. Each one is listed in the runner's guide given to every participant. Find out more:
