Knowing the UTMB® route means not only exploring the different distances and elevation gains available across the races on offer, but also finding out about cut-off times, the various time barriers in place and the available aid stations.

These figures have been verified against the official race sources. Please note that the route changes every year depending on weather and safety conditions, and may even be altered in the hours before the start: this was the case in 2026, when a storm caused a two-hour postponement and a last-minute change. The distance announced beforehand may also differ from the distance actually measured by the timing system: for the 2026 TDS®, official tracking shows 148 km and 9,300 m of elevation gain, with the finish recorded at 150.5 km.
The UTMB®, one of the four monuments of ultra-trail
Alongside the Western States 100 (United States), the Hardrock 100 (United States) and the Grand Raid de la Réunion (the Diagonale des Fous), the UTMB® is considered one of the four “monuments” of global ultra-trail. Its distance and elevation gain make it one of the most demanding races on the international circuit.
UTMB® history and records
The UTMB® is already a legendary race, and its history includes numerous records and an impressive list of big names. The 2026 edition also saw the first sub-19-hour finish in the race’s history. Find details of the UTMB® records, benchmark times and full results.
