3 Days of Gravel Stage Racing along the North Shore of Lake Superior.
You and your bike get on a bus in Duluth, you get dropped off at the Canadian Border. Over the next 3 days you ride back to Duluth. Your gear gets hauled in a box truck to each nights destination. You can stay in posh accommodations each night or you can dirtbag it the whole trip (respect). Entirely self supported out on course. Seriously, no one will come for you.
Marginal directions and Cue sheets are par for the course. Many roads unmarked. Route is mind blowing.
Winner gets a pat on the back.
