L'UMTLM offers a unique running experience with several formats to suit all levels of runner, around a demanding course between the resort of Thollon and the Mémises plateau:

• UMTLM 8 hours : The main challenge, in which riders attempt to complete the greatest number of climbs on a 3 000 m with 562 m D+ climb at 8 hours. Descents are made by gondola, allowing riders to rest.
• UMTLM 4 hours : A shorter version of the main event, with the same objective over a reduced time of 4 hours.
• UMTLM 2 hours : Ideal for those looking for a fast challenge, with as many climbs as possible in 2 hours.
• UMTLM Montée Sèche : An intense race over a single climb, with a mass-start, where the winner is the first to cross the finish line.
• UMTLM Rando : A more leisurely climb to enjoy the scenery, on the same 3 000 m and 562 m D+ climb.

Each format of the UMTLM offers a unique opportunity to test your limits and enjoy the atmosphere of this remarkable race, whatever your level or style of racing.
