22nd Annual Buffalo Headwaters Challenge

The Buffalo Headwaters Challenge presented by Adventure Subaru is a three-day, all-inclusive, “off the grid” mountain bike festival. It includes 5 meals, libations, primitive tent and RV camping, live music, and amazing trails, highlighted by the annual “Challenge” ride on Saturday, January 30th, 2027. The “Challenge” ride consists of a 35-50 mile semi-supported back country mountain bike experience. It’s a ride, not a race… just finishing is winning. There will be bailout options.
IMPORTANT! This is our annual fundraiser for the club and goes a long way in providing the needed tools and materials that go into the 10,000 hours plus volunteers put in each year. A large portion of this years proceeds will go directly into trail maintenance at the headwaters. With that in mind this is a non refundable event. If weather becomes an issue we will reschedule event to a later date but will not be offering refunds. Thank you for your understanding.
All attendees will receive a pair of custom event socks.
Complete your challenge and receive your patch once you check back in.

-A limited number of primitive RV spots are available for an additional $25.00. (no hook ups, you are paying for the space)
