Onboard camera, commentary, and power numbers from round 4 of the Lifetime Grand Prix, Chequamegon 40 mountain bike race. Part one is the battle for position into the Firetower Climb, and up and over Firetower which created the final selection. Part two is the final 7 miles of the race including the 6 person sprint for the win, plus a bit of the post race banter in the finish corral.
