Black Diamond Presents: What It Takes—Hillary Gerardi & The 90K du Mont-Blanc

Switching gears from shorter distances to a straight-up gnarly 90K ultra through the technical mountains of Chamonix is an admirable feat. But to win? That’s a tall order. For BD Athlete Hillary Gerardi, the transition to longer distances was a goal spawned by a winter of massive days on skis. Having completed the famous 110K Haute Route in a blistering 26 hours with her partner Valentine Fabre—in turn establishing the fastest female time for the route—Hillary felt ready to make the jump into ultra-distances.


First on her list this season was the 90K du Mont-Blanc. With roughly 6,000 meters of vertical gain packed into a technical course traipsing through the craggy alps, the 90K du Mont-Blanc is a true mountain testpiece of Chamonix.


But Hillary didn’t take on this beast alone. She had a crew of friends that put everything they had into seeing Hillary succeed. In this film, glimpse What It Takes to win an ultra-marathon.
