The first of three sky races in Olympic Valley this weekend. What is Skyrunning:
Skyrunning is a sport of mountain running up to or exceeding 2,000 metres (6,600 ft) where the minimum average incline is 6% over the total distance and at least 5% has an incline of 30% or more. The climbing difficulty does not exceed II grade UIAA. Poles, crampons and hands may be used to aid progress.
This weekend there will be a vertical kilometer (4 miles 3130' gain), a 52k, and a 26k race. There are individual podiums, as well as a podium for the Triple Crown winners. I will be doing the Vertical Kilometer race at Whiteface on July 2nd.
