A new, inclusive sports system
As of 2022, the UTMB® World Series integrates different levels of events.
UTMB® World Series Finals
The UTMB® World Series Finals will be held in the three key distances of the UTMB® Mont-Blanc - known as the OCC (50k), CCC® (100k) and UTMB® (100M). To qualify for a place at the Finals, trail runners must compete in at least one of the UTMB® World Series Events or UTMB® World Series Majors, where they can collect Running Stones for use in the lottery, or be rewarded for their performance with direct access.
The UTMB® World Series men's and women's titles will be awarded at these three races.

UTMB® World Series Events are the best trail running events on the planet and are organized to the highest quality standards, giving runners the chance to immerse themselves in the UTMB® experience on all continents.
Each year, three of these events will be given the status of UTMB® World Series Majors, becoming continental Series finals in the Americas, Europe and in Asia/Oceania.
