Question 1

What is the UTMB World Series?

Accepted Answer

The UTMB World Series is a global circuit of 64+ trail running races across five continents. Finishing a World Series race earns you Running Stones, which are required to enter the lottery for the UTMB Mont-Blanc finals (UTMB, CCC, OCC, TDS, MCC, and PTL).

Question 2

How do Running Stones work for UTMB qualification?

Accepted Answer

Running Stones are earned by finishing UTMB World Series qualifier races. The number of Stones awarded depends on the race distance and your UTMB Index score. To enter the UTMB Mont-Blanc lottery you must have accumulated the minimum required Stones for your target race (e.g. 15 for UTMB, 10 for CCC, 6 for OCC). Stones are valid for three years.

Question 3

When is the UTMB Mont-Blanc lottery?

Accepted Answer

UTMB Mont-Blanc pre-registration typically opens in January each year (January 2026 for the 2026 edition). You must have the required Running Stones before the registration window closes. Qualifier races run year-round, so runners often plan a full season of World Series races to accumulate enough Stones.
