The CCC (Courmayeur-Champex-Chamonix) is a 108km ultra-trail with around 6,200m of elevation gain, running from Courmayeur in Italy through the Swiss Val Ferret to Chamonix in France. The overall cutoff is 28 hours 30 minutes, and the highest point is the Tete de la Tronche at 2,584m, climbed in the first 10km.
CCC covers the second half of the UTMB course after its own brutal opening climb out of Courmayeur. The Tete de la Tronche climb (roughly 1,400m of gain in the first 10km) sets the tone; after Grand Col Ferret the course rolls through Swiss villages, and the 2026 edition dropped all the way to Martigny in the Rhone valley before the final climbs above Chamonix. Crew points are Champex-Lac and Vallorcine.

Finish time by age group
Every track runs from the start to the 28h30 cutoff, so the empty part of a bar is the time that group's median finisher still had. Men and women are drawn on the same scale.

How these numbers were computed
These are times for runners who finished. They exclude everyone who started and did not, so they describe how long finishing took, not how long the race takes. Bands with only a handful of finishers move a lot from one edition to the next.
We plot the median, not the average. A handful of very quick runners drags the average well below the time half the field actually beat, so the median is the honest number to plan against.
Nationality here shows who travels to this race, not who runs it best. That alone is why a host nation tops almost every list.

Ask the course
Ask CCC anything about climbs, pacing, crew or cutoffs.
Answers come from this course's data, your plan and your training.
Which climb should I respect most?
Courmayeur to Tete de la Tronche: +1,418 m over 9.4 km, straight from the gun. Hike the steep sections at an effort you could hold for hours - the race is decided after this climb, not on it.
Where can my crew meet me?
Champex-Lac, km 54.2 - the first of 2 crew points. The next is Vallorcine, km 90.1. Have them bring warm layers: the course tops out at 2,584 m, through the night, in August.
Is 22h a realistic finish for me?
22h would put you in the faster half of 2026 finishers - the median was 22:10:52. It means holding 12:15/km overall.

FAQ
How long is the CCC?
The CCC covers approximately 108km from Courmayeur (Italy) through Champex-Lac (Switzerland) to Chamonix (France), with around 6,200m of cumulative elevation gain. The 2026 edition was rerouted and ran 107.8km, seven kilometres longer than the 2024 and 2025 courses.
How much elevation gain does the CCC have?
The CCC has around 6,200m of cumulative elevation gain and slightly more loss over 108km, because it finishes 186m lower than it starts. The biggest single climb is the opening ascent to the Tete de la Tronche, roughly 1,400m of gain in the first 10km.
What is the cutoff time for the CCC?
The overall CCC cutoff is 28 hours 30 minutes, from the first wave at 09:00 to the finish barrier at 13:30 the next day. Later waves start behind the first, so each runner has that much less. Intermediate barriers apply at major checkpoints, and winning times are typically around 10 hours.
What is the highest point of the CCC?
The highest point of the CCC is the Tete de la Tronche at 2,584m, reached during the opening climb out of Courmayeur. The Grand Col Ferret (2,537m at km 31) is the second major high point.
How many aid stations does the CCC have and which allow crew?
The checkpoint table lists 12 major aid points between Courmayeur and the finish in Chamonix. Crew access is allowed at Champex-Lac (54km) and Vallorcine (90km); drop bags at Champex-Lac.
