The latest round of Megavalanche has started in the French Alps.
The event sees around 2,700 riders descend on mountain bikes from the summit of Pic Blanc at an altitude of 3,300 m all the way down to the lush meadows of the valley below at Allemont, a drop of over 2,000m.
Top competitors take less than an hour to complete the 32km course.
