The Voodoo (ALL-a-Toona)
June 21 @ 8:00 AM - 2:00 PM
Cobb County PARKS and MTB Atlanta invite you to the 10th Annual Voodoo/ALL-a-Toona Mountain Bike Race at Allatoona Creek Park, Georgia’s largest purpose-built mountain bike trail system! This challenging, 40+ mile, single-lap race uses nearly every trail, with a “half” version available for those not quite ready to tackle the whole thing. As always, this is an all-volunteer effort with 100% of the proceeds being used to build and maintain the park’s trails.
