No refunds will be issued, as this is a fundraising event.
The bike courses consist of a 3 and 6-mile loop on mountain bike trails with single and double tracks. The three-hour race is designed for beginner-intermediate riders, with the six-hour course geared toward advanced riders. Participants will complete as many laps as possible during a 3-hour or 6-hour time duration. The race can be completed as a team or by an individual. The START/FINISH line will be in the meadow area of the Big Hill Trailhead (Trail # 72), by the warming hut.
The 6-mile bike loop will start by leaving the meadow area at Big Hill Trailhead and descending down Twin Bridges heading in a clockwise direction for approximately 1.5 miles. You will then stay right and climb up a double track approximately 1 mile to a ridge that will lead you to “C” Loop. Once on “C” Loop you will descend to “A” Loop which will lead you back to the meadow area of the Big Hill Trailhead.
The trail run is structured very similar to the bike race. With the option for a 3 hour or 6 hour race. Completing as many loops as possible on a 3 mile loop. Choose to take on the challenge by yourself, or gather a team!
There will be aid stations at the START/FINISH line area, one for the bikers and one for the runners. Lunch will be provided for all participants.
