Who will triumph in the Octagon?! This challenging bike event hosted by Southwind Cycle and Outdoor in Humboldt, KS pits 100 miles of Kansas gravel punctuated by eight sections of gnar against your legs, bike and bike handling skills. Not quite up for entering the Octagon? Try the 50-mile Square or 25-mile Line rides for a little bit less ridiculousness but just as much small town fun.
