Method and sources

Stones recorded from each race's utmb.world page, last updated October 31, 2026.

Km per stone = distance ÷ stones; elevation gain per stone = elevation gain ÷ stones; effort-km per stone = (km + elevation gain/100) ÷ stones. Continent deduced from race country.

FAQ

How many Running Stones do you need for UTMB?

Stones aren't a threshold: each stone is one extra ticket in the UTMB Mont-Blanc draw. A 100M earns 4, a 100K earns 3, a 50K earns 2, a 20K earns 1; a Major doubles these values.

How many UTMB World Series races in 2027?

217 races in the RAVIT catalogue, of which 177 have their 2027 stones listed on utmb.world.

Which 2027 race gives a stone for the fewest kilometres (km per stone)?

Val D'Aran - EXP - Experiència d'Aran: 8.3 km per stone.

What's a Major?

A race in the UTMB World Series Majors: its stones count double (8 for a 100M, 6 for a 100K).

Why «to be confirmed»?

The race's utmb.world page hasn't published its 2027 stones yet: the race stays listed, but excluded from stone sorts and the report.
