The Numbers of UTMB 2026

10,566 runners participated in the seven races: TDS, MCC, ETC, PTL, OCC, CCC, UTMB in 2026. I did not include the YCC youth races in this calculation. That’s about a 2% reduction in field size, which feels like a rounding error and don’t think indicates a trend.
The more interesting numbers to compare are the individual races. It seems UTMB really reshuffled the number of runners they allowed in several of the races. Here are the starters for each of the race compared with previous years:

	2024	2025	2026
UTMB	2,761	2,492	2,407
CCC	2,270	2,127	1,974
OCC	1,764	1,568	1,945
TDS	1,874	1,934	1,290
MCC	1,147	1,198	1,456
ECC	1,216	1,332	1371
PTL*	120	121	123

*PTL show numbers of teams.

TDS saw a huge drop in starter numbers, and a smaller drop for CCC. These numbers which were redistributed to MCC, OCC, ETC – the shorter distances. Is this a fluke, a response to the fairly high DNF rate in the longer distances, or UTMB trying to reduce the number of runners on the trails for sustainability purposes, I don’t know.

UTMB Week 2026 had 10,566 runners starting the various races (again, not counting the youth races). And there were a combined total of 8,246 finishers. 2,227 (27%) women and 5,935 (73%) men reached the finish line (I took the PTL team event out of this calculation here.) That’s a 2% (finisher!) growth in women participation over last year.
