Downhill, cross-country and mountain biking... no less than three disciplines are being held this Saturday and Sunday for nearly 300 bikers. The mountain biking section of the Chamonix "Club des Sports", numbering a hundred members, is organizing a regional event double: races for the youngest children, and also for older children from the younger "Cadet" group. The Junior Downhill event will be held at the Gaillands on Saturday. Then on Sunday, everyone will be at the "Désert Blanc" for the Mountain Bike and Cross-Country events.
