How to participate in the UTMB?

The Ultra-Trail du Mont-Blanc (UTMB) is a mountain ultramarathon race, first organized in 2003, following the route of the Tour du Mont-Blanc. It is considered the most competitive trail ultramarathon in the world.

The race takes place once a year during the last weekend of August or the first weekend of September in the Alps. It follows the Tour du Mont-Blanc route through France, Italy, and Switzerland. The distance is approximately 171 kilometers and the total elevation gain is around 10,040 meters.


UTMB Index, Running Stones, and MyUTMB+ explained

Would you like to prepare your participation in the UTMB, CCC, or OCC? Or simply understand the benefits associated with the UTMB Index races on our calendar?

Here is the essential information to help you choose your races and navigate between UTMB Index, Running Stones, and MyUTMB+ points.

To keep it very simple, here is the rule to remember:

A valid UTMB Index in an accepted category + at least one Running Stone obtained in the last 24 months = entry into the lottery for a UTMB Final.

Your Index allows you to aim for a final in the same category, lower categories, or the category immediately above

You must then pre-register during the official period. Each Running Stone represents one entry in the draw.

In 2026, approximately 29,000 applications were registered for the draw for the three UTMB World Series Finals.
