Skiing downhill can burn, too. A-Basin’s Enduro, on April 13th, is a test of how much pounding your legs can take. The Pallavicini lift turns from 7-5 and teams of two crank through as many laps as they can in that time. The double chair turns slow, the terrain is steep and unforgiving, and the record is 71 runs. We hear some racers wear diapers so they don’t have to stop.
