Inca Avalanche is a mass start enduro style downhill mountain bike race. Starting at nearly 16,000 feet of altitude on the backside of one of the 7 Wonders of the World - Machu Picchu, the Inca Avalanche is one of the highest races in the world. The race is not broken into different stages but rather one continuous run from the start to the finish line - about 5900 vertical feet of descending over approximately 25 minutes, depending on your level of shred!  An annual even in Ollantaytambo, usually last weekend of April.
