Megavalanche 2025

Megavalanche 2025. The legendary adventure awaits you! For those who don’t know yet, the alpe d’huez megavalanche is one of the most legendary and unmissable marathon descents in the world!

Ouvertures du vendredi 4 au dimanche 6 juillet 2025. The mass start on the snow is the most iconic part of the megavalanche, with a huge pack of riders hurtling down a snowy glacier at speeds like 75kmph, mostly out of control.
