The 7th Annual Black Hills Super 6 Mountain Bike Race will be held on Saturday, August 16, 2025, at Big Hill Trails. We are excited to announce the addition of an inaugural trail run. The bike race and trail run will occur simultaneously, on separate course. Early bird registration opens on June 1.
Enjoy the Black Hills National Forest and help raise money for Northern Hills Area CASA, a non-profit 501 (c)(3) organization. Northern Hills CASA (Court Appointed Special Advocates) promotes and protects the best interests of abused and neglected children through the advocacy efforts of trained volunteers. All proceeds benefit victims of child maltreatment in eight counties of western South Dakota.
The Black Hills Super 6 Mountain Bike Race is intended for participants of various ages and ability levels. The 3-hour/3-mile bike loop is designed as a short course for beginner riders. The 6-hour/6-mile course is geared for intermediate-advanced riders.
Utilizing Big Hill Trails, there will be a 3- and 6-mile loop on mountain bike trails which consist of flowy single track and double track. 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 solo. The START/FINISH line will be in the meadow area of the Big Hill Trailhead (Trail # 72), by the warming hut.
The 6-mile 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 Black Hills Super 6 inaugural trail run offers 3- and 6-hour options, with both utilizing a 3-mile loop, separate from the bike courses. The 3-hour run can be completed as an individual or as a 2-person team. Gather your friends and form a team (2-4 participants) for the 6-hour event, or go solo, if desired. Participants will complete as many laps as possible during a 3-hour or 6-hour time duration. There will be a separate aid station designated for runners. Having two types of races occurring simultaneously is a unique opportunity, all in support of the CASA Cause.
