The three timed events will take place over 4 full days, Friday, October 9 through Monday, October, 12.



The race courses are a scenic mix of challenging climbs and descents through Willow River State Park. Run along the banks of the Willow River, past beaver ponds, and across the base of breathtaking Willow Falls.

Choose among 6.6K, 10.6K, or 21.1K (Half Marathon) distances. Each race is not only longer but more challenging than the last!
