Taking in to account the success of the event and the very large number of requests, registration for the UTMB^® races is governed by two principles : a points system, for runners who have previously completed qualifying races, and a draw.

This system ensures that the runners have the experience necessary to participate in one of the UTMB^® races, and it manages the number of participants so that the races take place in good conditions (quality, safety and with respect for the environment).

The organisation offers 4 individual races (UTMB^®, CCC^®, TDS^®, OCC and MCC) and an adventure in teams (PTL^®) meaning welcoming almost 10 000 participants coming from 100 different countries.

Those persons not selected by the draw, benefit from advantageous conditions valuable for the same race at the time of registration the following year, which would double their chances. For those who are not selected two years in succession, there is a priority registration (upon the understanding that they have the necessary points).

All the information concerning pre-registration and registration are available below.

International ELITE runners benefit from specific registration conditions on the event according to precise criteria based on their ITRA performance index.
