Registered participants and stars
There is a simple way to view the list of registered participants for the 2025 races, find a friend or club member, and discover which trail stars will be on the start line this year. A page on the UTMB® website will give you all this valuable information.
How to follow the race live
There is a very convenient way to follow the live coverage of the main UTMB® races. The website lets you track your friends and favourite runners and experience the race as if you were right there!
Mandatory gear
For safety reasons, the organisers require a fairly comprehensive list of mandatory gear. This includes technical and specific clothing for trail, as well as survival equipment and safety gear, a minimum food supply to carry, and weather kits to have on hand in case of extreme weather conditions.
The ultra trail expo
Beyond the races, the UTMB® is also a unique chance to meet industry professionals and discover their latest innovations. The ultra trail expo is a must-attend event to choose your next kit, test products, and even find new destinations for your future trails! Find the full details of all events on the official website.
