Rib Mountain Adventure Challenge Logo

Are you up for the Challenge? 

The Rib Mountain Adventure Challenge is an adventure race in which teams of 2-4 members will run, bike, and paddle through the rugged and beautiful Central Wisconsin wilderness on an unmarked course, using only a map and compass to find the way. Team members must stick together throughout the duration of the race. With plenty of route choices and obstacles to test your team’s physical strength and mental resolve, this race will be fun for beginners and seasoned athletes alike. 

Choose either the 3-hour or 8-hour challenge.
