The HOKA UTMB Mont-Blanc is the most incredible trail running event! Each year, the best athletes meet in Chamonix and more than 10'000 runners participate in one of the event's 8 races, including the UTMB World Series Finals. Since its start in Chamonix in 2003, and building on that success ever since, the HOKA UTMB Mont-Blanc has grown to be the world's leading trail event and is the inspiration behind the creation of the UTMB World Series circuit, based on the same founding principles: surpassing one's limits, fair play, respect for people and the environment and solidarity. Starting in 2023, the HOKA UTMB Mont-Blanc will host the prestigious UTMB World Series Finals each year, crowning champions on its three iconic races: UTMB, CCC and OCC.
