UTMB Mont-Blanc Registration Numbers 2026

(Linking here to the press area on their website for the UTMB Finals, but the information I gathered is from their press email). Here are some of the highlights:

• 29,000 applications were registered for the UTMB World Series Finals draw

That’s almost 30K people who want to run one of the three Finals races: UTMB, CCC, OCC. In 2025 there were combined about 5,200 starters at the starting line for these 3 races combined. So these races are about 5 times oversold. Demand is not slowing down.

• 11 – This is the average number of Running Stones held by runners drawn for the UTMB, compared with 7 for the CCC and 5.5 for the OCC.

In 2025 for UTMB you needed (on average) 5.4 stones, in 2024 5.3. So for 2026 this doubled. If you want to see a graph, where the probability is broken down by race and number of stones, UTMB created one for you.

• 2/3 – Two-thirds of runners registered for the draw selected the boost, committing to travel to the Mont-Blanc valleys via a lower-carbon route, without using a car.

This is obviously a new number and has no comparison yet. It’ll be interesting, but I doubt we will ever see any numbers, if anyone get’s kicked out for declaring, but failing to follow through. Like… carbon cheaters?

• 76% of participants are European

Last year’s numbers were 75%.

• Women account for 26% of the field

A nice increase from 20% in 2025, but still not Tarawera – numbers.

And from Isabelle Viseux-Poletti, UTMB France Director:

The draw unfortunately leaves many runners without a bib, and we recognise how legitimate that disappointment is, given the time, energy and hope invested.
…
[F]or regulatory reasons and out of responsibility towards runners, volunteers and the region, the number of race bibs must remain strictly limited and cannot be increased.

So, don’t expect getting a bib for the Finals in Chamonix to get any easier in the coming years.
