What is the UTMB Index in trail running?

The UTMB Index is an international performance ranking system designed to evaluate trail and ultra-trail runners. Each certified UTMB Index race result generates a score based on course difficulty and finishing time.

The index is divided into distance categories (20K, 50K, 100K, 100M) to accurately reflect an athlete’s strengths. It is calculated from the best recent performances rather than a single race, creating a fair, stable, and globally recognized rating. Competing in UTMB Index races helps runners build a credible performance history on the international stage.
