Megavalanche is a mountainbike downhill marathon style event. The most famous round is run from the French Alps town of Alpe D'Huez, starting on the glaciated summit of the Pic Blanc (3,300m) and descending to the lush meadows of the valley bottom at Allemont (720m), after some 2000 metres down and 30 km along. The format of the event follows three main days: Around 2,700 participants will depart the summit of the Pic Blanc with top competitors making the 2000m descent in less than an hour (00:38:28 in 2013). Other rounds of the event take place in Peru and Reunion Island.
