About the Event

Test your limits at one of America's most demanding self-supported mountain bike challenges, the Marji Gesick. Held in Marquette, Michigan from September 18-20, 2026, this race is a legendary proving ground on the rugged trails of Michigan's Upper Peninsula. The event operates on a strict self-supported ethos, requiring riders to navigate over 100 miles of rocky, root-filled singletrack with relentless climbs and unpredictable weather. It's more than a race; it's a personal journey to find your absolute limit, famously described as "the hardest single-day mountain bike race in America." Registration for the 2026 edition opens on October 17, 2025, and a dedicated training camp in June helps athletes prepare for the unparalleled challenge. Created to honor the Ojibwe leader Mah-je-ge-zhik, the race demands mental grit as much as physical endurance, offering a brutally authentic adventure where finishing is the ultimate victory.
