The event will also leave a lasting legacy for the region: thanks to charity bibs and the 80K Relay, more than CAD 117,000 has already been raised in support of the Fondation Tremblant and the Québec Epilepsy Association (AQE). In addition, the thousands of participants, their companions, and 370 volunteers are expected to generate more than CAD 8 million in economic impact for the region.

HOKA UTMB® Mont-Blanc continues its commitment towards a more responsible event
True to its commitment to more responsible trail running, the HOKA UTMB® Mont-Blanc continues to develop initiatives in close collaboration with local authorities to reduce its impact on the territory and help preserve the Mont-Blanc massif. The number of participants has been capped for more than ten years in consultation with local municipalities, while the UTMB® Mobility program continues to expand to reduce car travel through an extensive shuttle network, additional train services between Saint-Gervais and Chamonix, and free access to selected cross-border transport routes. The event also works to protect biodiversity by adapting certain race courses, introducing mandatory red-light headlamp mode through the Contamines-Montjoie Nature Reserve to minimize disturbance to nocturnal wildlife, and deploying around thirty environmental ambassadors to raise awareness among participants while helping maintain more than 1,000 kilometres of trails before and after the races.
The HOKA UTMB® Mont-Blanc is also committed to making trail running more inclusive and supportive. Through its Adaptive program, 58 athletes with disabilities, up from 37 in 2025, will be able to experience the event under adapted conditions. The event also works to promote greater equality by implementing practical measures that address the needs of female runners, including the provision of feminine hygiene kits, dedicated changing areas at all aid stations, and dedicated meeting spaces for participants, as well as the Path to Parenthood initiative, which supports athletes before, during and after pregnancy. Solidarity bibs also enable participants to support charitable organizations through fundraising during registration: in 2025, €445,000 was donated to around twenty organizations, the majority of which are based within the territories crossed by the event. At the same time, the event continues to reduce its environmental footprint through increased sourcing from local producers, vegetarian aid stations and a waste reduction and recovery policy, with 79% of waste recovered in 2025.
