These training plans are built for runners who know what they're getting into. The Mont Blanc massif means sustained climbing through two full nights, technical descents that'll wreck your quads by 80km if you haven't prepared them properly.

Over 20 weeks, you'll build what UTMB actually needs. Quads that can handle massive descents and the technical skills to deal with rocky trails and scree fields at 3am when you're running on fumes.

Training sessions mirror what you'll face out there: big sustained climbs up to the high passes, long punishing descents on tired legs, back to back mountain days so you know what running through multiple nights feels like, and the pacing discipline to not get carried away in the first 30km and blow up spectacularly at Courmayeur.

You'll get purposeful vertical volume, strength sessions focused on keeping your quads intact, night running and fueling strategies that hold up.
Whether you're aiming to finish under the arch in Chamonix or chasing a solid time, this plan prepares you for what UTMB will actually throw at you.

By race day, you'll know how to pace the nine major climbs without destroying yourself, get down 10,000m of descent without your quads giving up and keep your head together when altitude, darkness, and fatigue all hit at once.
