CCC course map and aid stations

The 100K of UTMB week: from Courmayeur over the Grand Col Ferret into Switzerland, then back into France to finish in Chamonix.

2027 dates not announced yet, usually in August Courmayeur, Italy to Chamonix, France

The CCC is the 100K race of HOKA UTMB Mont-Blanc and the 100K final of the UTMB World Series. First run in 2006, it starts on the Friday morning of race week in the middle of Courmayeur, climbs straight to about 2,500 m facing Mont Blanc and the Grandes Jorasses, and crosses the Grand Col Ferret into Switzerland. From La Fouly, Champex and Trient it comes back into France at Vallorcine and finishes in Chamonix.

The map shows the 2026 course as the organizer planned it, 101.4 km with 6,015 m of climbing. The 2026 race itself was rerouted through Martigny for the weather. The 2027 course isn't out yet.

You need a working phone to race (the organizer says airplane mode is forbidden), and the regulations warn of areas where only emergency calls go through. Download the map before you go: GPS shows where you are without a signal.

The race opens with more than 1,300 m of climbing, from 1,221 m in Courmayeur to Tête de la Tronche at 2,543 m, in under 10 km. You drop to Refuge Bertone and run on past Refuge Bonatti to Arnouvaz, then climb to the Grand Col Ferret, 2,527 m, and the Swiss border. Champex-Lac at 55 km is the one stop with your drop bag and the first aid station where your crew can meet you. Vallorcine is the second.

After Champex you pass Plan de l'Au, which has a cutoff (Sat 00:15) but no aid, then climb over La Giète and drop to Trient. From there you go up past Les Tseppes and down to Vallorcine. The last climb is to La Flégère at 1,875 m, a drinks-only stop 7 km above the finish. The stops and cutoffs are the race page's for 2026.

Getting into the CCC

Entry is by lottery. You need at least one Running Stone earned in the past two years, and every Stone you hold puts your name in the draw once more. You also need a UTMB Index in the 50K, 100K or 100M category. Stones come only from UTMB World Series races, and the CCC doesn't give any: as a Final, it was left out of the 2026 Stones. Winning a World Series race can also get you in directly.

The 2026 fee was €310, plus an 8% administration fee, and it covered the bus to the start. Entries are personal, and there's no refund without cancellation insurance. The 2027 dates weren't announced when this page was checked.

The race runs buses to the start, and your entry covers them. Book your seat in MyUTMB by the deadline (July 12 in 2026); no bookings are taken after it. After the race, Arriva runs the return to Courmayeur for anyone showing a bib.

For Chamonix, the organizer puts Geneva airport about 1 hour 30 away and Lyon Saint-Exupéry about 2 hours 30, with buses and trains from both, and asks you not to rent a car.

Crews can meet you at Champex-Lac and Vallorcine. Only one person may help, in the area set aside for it, and all they can give you is a bag of up to 30 liters, plus a massage or a blister fix while you sit. Nobody may run with you outside the marked spectator zones.

Roads to Courmayeur, La Fouly, Champex, Trient and Vallorcine are closed to private cars during the race, and the CCC can only be followed on the UTMB Mobility coaches. A 2026 pass for one adult cost €31 for the Italian side and €36 for the Swiss side, and passes sold only from June 9 to July 12. Vallorcine is also on the Mont-Blanc Express train.

Weather and kit

August in Chamonix averages a high of 23.1°C and a low of 8.7°C (Météo-France, 1981 to 2010). The race warns that August in the Mont Blanc range can go over 30°C or down to -10°C above 2,000 m, with rain, hail or snow. The 2026 race was wet and muddy.

The CCC kit includes a hooded waterproof jacket and waterproof overpants, a warm second layer, a beanie, warm waterproof gloves, two headlamps with backup power, a survival blanket, a whistle, 1 liter of water (1.5 recommended), a 15 cl cup, and a phone with the LiveTrail app and roaming in all three countries.

CCC FAQ

When is the CCC 2027?

The 2027 dates hadn't been announced when this page was checked. In 2026 the CCC started Friday August 28 at 09:00 in Courmayeur, in the race week of August 24 to 30.

How do you get into the CCC?

Through the lottery, with at least one Running Stone from the past 24 months and a UTMB Index valid in 50K, 100K or 100M. Each Stone is another entry in the draw. Winning a UTMB World Series race can also get you in directly.

How long is the CCC?

The 2026 course as planned was 101.4 km with 6,015 m of climbing, and the finish cutoff in Chamonix was noon on Saturday.

Does the CCC give Running Stones?

No. The 2026 Running Stones at HOKA UTMB Mont-Blanc left out the Finals, and the CCC is the World Series' 100K Final. Finishing still gives you a UTMB Index.

Where can crews meet runners on the CCC?

At Champex-Lac and Vallorcine on the 2026 course, one person per runner, reached by UTMB Mobility coach (or the train to Vallorcine). Champex-Lac also has the drop bag.

Who won the CCC in 2026?

Cristian Minoggio in 10:21:48 and Yngvild Kaspersen in 12:01:14. Kaspersen became the first woman to win the CCC twice.
