What is the Defiance Challenge?

It’s an endurance event, open to expert skiers and riders age 6 and up, to see which two-person team can complete the most runs in 10 hours. The record was set in 2020 by the team of Aidan Corcoran and Nate Grosscup, with 49 runs, for a total of 66,792 vertical feet. The Defiance Challenge gets underway at 7 a.m. outside the main Sunlight lodge with a Le Mans-style start. At the sound of the starting gun, participants sprint to their waiting skis or snowboards, clip into their bindings, then scramble in a mad rush to the nearby Segundo chairlift that will take them to the top of their first run. Over the next 10 hours, teams ski or ride down 40 different routes, including every double  black diamond run.
