Snowbasin by UTMB is the start towards your quest to the UTMB World Series Finals in Chamonix, the mythic HOKA UTMB Mont-Blanc, the holy grail of trail running in the heart of the Alps, set on the three key distances: OCC (50K), CCC® (100K) and UTMB® (100M), the pinnacle trail running event.

As a UTMB World Series Event, the Top 3 female and Top 3 male runners of the 58k at Snowbasin by UTMB gain automatic qualification to the OCC.

All finishers of the Snowbasin by UTMB collect Running Stones that can be applied to the HOKA UTMB Mont-Blanc draw. To be eligible for the lottery, runners need to have a least one Running Stone and a valid UTMB Index.

The UTMB World Series strongly believes in equal rights and opportunities for all members of the trail-running community. We are in the process of building inclusion and diversity policies on gender, race, age, social class and more. We endeavour to grow and continue to evolve the sport and to make UTMB World Series welcoming for each athlete.
