30 MILE Black Hills CrossFit Edition
Singles
Team of 3
Team of 6
The event is wrapped around the 30 Mile Lean Horse Ultra Marathon. Teams will start with a Black Hills CrossFit movement. After the first movement is completed the first runner will proceed to the first aid station. At each aid station there will be a movement and once completed the next runner will move on, and so on until the last runner crosses the finish line. All movements are posted. Your team can decide who will do each challenge and leg of run. For teams of six, each teammate must complete one of the CrossFit movements followed by one leg of the race. For teams of three, each teammate must complete two of the CrossFit movements and two legs of the run. The movements will be chosen from standard Black Hills CrossFit movements. Each team will receive a competition t-shirt per athlete. The event will begin at the Custer track, follow the Mickelson Trail, turn around at the Hill City Aid Station, and end back at the Custer track. Top teams will receive a Champion Award for each teammate. All athletes that finish the event will receive a Finisher’s Award.
