After a failed first attempt 2 years ago, watersport master Kai Lenny attempts to windsurf 56 miles across Lake Michigan. Better equipment, a better forecast, and a different location set the stage for his second attempt, and it all falls onto Kai to power through hours of constant focus and bitter cold to pull it off. After 2 hours and 50 minutes of windsurfing through endless choppy waves, Kai emerges triumphant on the other side of the lake.Subscribe to Red Bull on YouTube for a constant bombardment of tasty content: http://www.youtube.com/subscription_center?add_user=redbullLearn more about prodigy Kai Lenny and all other Red Bull athletes here: http://www.redbullusa.com/cs/Satellite/en_US/Profile/Kai-Lenny-021242752635790
