In the realm of ultramarathons, few events rival the prestige and challenge of the Ultra-Trail du Mont-Blanc (UTMB). Since its inception in 2003, this grueling race has evolved into a monumental pilgrimage for trail runners worldwide. Each August, the picturesque town of Chamonix, nestled at the feet of Mont Blanc, transforms into a vibrant hub filled with the echoes of cowbells, palpable nerves, and dreams woven into trail shoes.
The flagship event, the 100-mile loop around Mont Blanc, traverses the borders of France, Italy, and Switzerland. Participants face an astonishing ascent of nearly 10,000 meters, navigating through alpine passes and charming historic villages. This race is not only a test of endurance but also a journey that remains etched in the minds of those brave enough to finish.
For the upcoming race, there will be a small course reroute due to landslides, and the famed La Balme aid station will be excluded. Nonetheless, the heart of the race remains unscathed, with the finish line still proudly situated in the heart of Chamonix.

The 2025 Courses: What to Expect
UTMB (Ultra-Trail du Mont-Blanc)
The main attraction, the UTMB race spans an impressive 108 miles (174 km) and presents nearly 33,000 feet of elevation gain. It starts in Chamonix with an electric atmosphere, fueled by thousands of spectators and a palpable sense of anticipation.
Runners embark on their journey through breathtaking landscapes, negotiating tough terrains of Les Contamines, Col du Bonhomme, Courmayeur, and Grand Col Ferret. Each ascent and descent tests not just physical limits but also mental fortitude. As competitors enter Switzerland, the iconic landmarks become almost mythical. Reaching locations like Champex-Lac and Trient serves as both a moment of rest and a strategic juncture in the race.
The trek back to Chamonix culminates in a final descent that occasionally demands every ounce of energy remaining in the runner’s reserves, confirming that UTMB is quintessentially more than a race; it’s a life-altering experience.
CCC (Courmayeur, Champex, Chamonix)
Though the CCC (101 kilometers or 62 miles) is shorter, it is far from less intense. Beginning in Courmayeur, runners are immediately faced with challenging climbs. The transition to Grand Col Ferret, which leads into Switzerland, provides those daunting views followed by gripping ascents and descents that continuously test stamina.
This race is often regarded as a proving ground for runners eyeing the UTMB, making it a coveted challenge for elite and recreational participants alike, merging a demanding course with a breathtaking alpine backdrop.
OCC (Orsières, Champex, Chamonix)
Don’t underestimate the OCC’s 55K distance, as it tests every participant to their limits. Starting in Orsières, runners face immediate challenges, with steep climbs and technical sections dominating much of the course. The high-paced nature of this race makes it both appealing and daunting, often requiring competitors to strategize their efforts from the onset.
Those racing this shorter distance may come from varying backgrounds, but they all share a passion for trail running that contributes to a highly spirited event.
Prize Money Breakdown for Competitors
Given the international status of the UTMB, it’s no surprise that the total prize pool exceeds $400,000. Here’s a brief overview of the prize money allocated for the main event:
- 1st Place: €20,000
- 2nd Place: €12,000
- 3rd Place: €8,000

Similarly, both the CCC and OCC races will award elite competitors, with each offering €76,000 in prizes.
Women’s Race Preview
This year, all eyes are on Courtney Dauwalter, who makes her return after a hiatus from the race. Her impressive performances at Hardrock and Lavaredo demonstrate her readiness. However, the competition is fierce, with Ruth Croft eager to challenge her past performances and Abby Hall, who has garnered momentum with a recent win at Western States.
With talents like Katharina Hartmuth and Camille Bruyas also in the mix, it’s poised to be a fiercely contested event.
Men’s Race Preview
The 2025 men’s race promises to be a thrilling showdown with no clear favorites, emphasizing the unpredictable nature of ultra racing. While Jonathan Albon stands out as a top contender, François D’Haene aims for a historic fifth victory. Add in names like Hayden Hawks and strong local talent from France, and it’s evident that this year’s race could unfold in unexpected ways.
As they tackle the trails of Mont Blanc, only those with resilience tend to emerge victorious.
