Shelden's BIG Bang XC MTB Race
About this race
A traditional XC MTB race has returned to Stony Creek Metro park, and its Shelden Trails in Shelby Township, MI. Mashing up exciting machine built single track, an old school climb trail, and classic two track, an 8.5 mile lap is on tap for racers. Push hard and try to get that top step, beat your friends, or push yourself in your first mountain bike race on some of Southeast Michigan's favorite trails.
After the half-mile hole shot and prelude from the start line, the 8.5 mile lap -- split 60/40 between single and two track -- features six unique single and two track sections per lap, perfect for testing your handling and having fun while offering wide-open, fast, safe areas to pass. Steady climbs, flowing descents, and lots of fun and excitement await!
All post race proceeds donated to the House of Promise (Lansing, MI) for human trafficking victim rehabilitation.
