Get ready to explore some stunning scenery in the Lewis and Clark National Forest northwest of Helena while supporting a great cause—all proceeds go to help kids with diabetes attend summer camp through the Montana Youth Diabetes Alliance. You can pick your own adventure with the Bumbler (26 miles) for a mellower experience or tackle the Rumbler (55 miles) featuring 4,000+ feet of elevation gain on forest service roads with some technical climbs that reward you with epic descents. Bonus: you'll ride sections of the legendary Tour Divide route along the Continental Divide!
