The UTMB®: one of the four monuments of ultra-trail
Alongside the Western States 100 (USA), the Hardrock 100 (USA) and the Grand Raid de la Réunion (the Diagonale des Fous), the UTMB® is regarded as one of the four "monuments" of world ultra-trail. Its distance and elevation make it one of the most demanding races on the international circuit.
