The Megavalanche in Alpe d’Huez is one of the most iconic mountain bike races in the world, attracting adrenaline seekers and competitive riders from across the globe. Famous for its mass start on the snow-covered Pic Blanc glacier and epic descent to the lush village of Allemont, the race is a bucket-list experience for mountain bike enthusiasts visiting the French Alps.
What Is the Megavalanche?
The Megavalanche is a marathon downhill mountain bike race held annually in July at Alpe d’Huez. The course stretches from the glaciated summit of Pic Blanc (at 3,330 m) down to Allemont (at approximately 720 m). Riders navigate 20+ kilometres of varied terrain, including snowfields, gravel, technical singletrack, and Alpine meadows—making this race a true test of skill, fitness and courage.
Who Can Compete?
The Megavalanche welcomes amateur and professional riders alike. Participants need good technical skills and should be confident riding steep, loose, and mixed surfaces. The race weekend also features events for different categories, including women, e-bikes and juniors, so riders of all backgrounds can get involved.
Essential Preparation Tips
- Equipment: A full-suspension mountain bike in excellent condition is essential. Wide tyres with mixed tread, effective brakes, and reliable suspension will help on both snow and rock gardens.
- Clothing: Layer up with moisture-wicking base layers, windproof outerwear and gloves. Helmets are mandatory, and many riders choose goggles for the snowy section.
- Training: Practise technical descents and endurance rides. If possible, arrive early to acclimatise to the altitude.
