LevelVery Hard
Billed as the hardest single-day mountain bike race in America, running 18–20 September 2026 across the singletrack of Michigan's Upper Peninsula. Fully self-supported with no race aid stations, a 12-hour cut-off and a famously low finish rate. Bike distances of 50, 100 and 200 miles plus run categories.
