2026 applicants rounded, from the organizer as reported by Run247. Starters: live.utmb.world. Chances: our calculation, starters divided by applicants, so orders of magnitude. Bibs outside the lottery (elites, charity bibs) lower the real rate, entrants who do not start raise it. Coming without a car raises your chances by 30% (UTMB, CCC, OCC, ETC). You can enter only one lottery race per year.
How do you enter each UTMB race?
All go through the January entry window, but not the same way: the UTMB, CCC and OCC are drawn by lottery weighted by Running Stones, while the TDS goes to the first to sign up. You can only try one race in the draw each year.
How do you enter the UTMB?
Through the January lottery, weighted by Running Stones, after finishing a 100-mile race in the UTMB World Series. About one chance in four in 2026 (~23%, our estimate: 2,406 starters for nearly 10,400 applicants). 174 km, 10,000 m of climbing, €439 (2025 price).
How do you enter the CCC?
Through the same January lottery, weighted by Running Stones. It is the easiest race to get: ~27% in 2026 (our estimate: 1,974 starters for nearly 7,200 applicants). 107.8 km, 6,200 m of climbing, €285 (2025 price).
How do you enter the TDS?
No lottery: places go to the first to sign up, in January. 148 km, 9,300 m of climbing, €290 (2025 price). It is the hardest to finish: 715 finishers out of 1,290 starters in 2026.
How do you enter the OCC?
Through the January lottery, weighted by Running Stones. It is the most sought after: ~17% in 2026 (our estimate: 1,945 starters for nearly 11,400 applicants). 60 km, 3,500 m of climbing, €179 (2025 price).
Who can run the MCC?
Only local residents, volunteers and partners, through a draw reserved for them. 40 km, 2,350 m of climbing. Price and odds not published, to be checked.
How do you enter the ETC?
Through a draw open to all, without Running Stones. 15 km, 1,200 m of climbing, €59 (2025 price). Odds not published.
How do you enter the PTL?
Through a team pre-registration of 2 or 3 runners. Odds not published.
Odds: our calculation, 2026 starters (live.utmb.world) divided by applicants (organizer, reported by Run247), so orders of magnitude. Prices: 2025 rates from the official website. Checked on October 27, 2026.
