Four majors, four chances to double your Stones
The UTMB World Series Majors are the pinnacle events of the season on each continent. These are the only races where athletes can double their Running Stones, increasing their chances of qualifying for the UTMB World Series Finals in Chamonix.
Running Stones are the official currency of the UTMB World Series qualification system. Runners earn them by finishing UTMB World Series races. The more Running Stones a runner collects, the more chances they have in the lottery to enter the UTMB World Series Finals in Chamonix.
In 2025, the Majors are:
- Oceania Major: Ultra-Trail Australia – May 15–18
- Europe Major: Val d'Aran – July 2–6
- America Major: Kodiak Ultra Marathons – October 10–11
- Asia–Pacific Major: Chiang Mai Thailand – December 5–8
