MKULTRA Gravel

MK Ultra Gravel is a free, 100-mile gravel cycling event on June 7, 2026, starting from the Marquette Fire Bell in Marquette, MI. Inspired by the CIA’s infamous experiments, the ride features seven rowdy, technical gravel sectors rated Paris-Roubaix style (1–5 stars) with Grinduro-style timed segments and KOM/QOM challenges through Marquette County’s wildest terrain. There is no entry fee — just a suggested $10 donation to Great Lakes Recovery Centers.
