About this event
Why MK Ultra?100 miles — 3,595 ft elevation gainThe CIA ran Project MKULTRA from 1953 to 1973. It was a covert program of illegal experiments on unwitting human subjects — testing LSD, hypnosis, sensory deprivation, and psychological torture. Subjects included mental patients, prisoners, drug addicts, and ordinary citizens who never consented.The program funded research at 44 colleges and universities, 15 research foundations, 12 hospitals, and 3 prisons. CIA Director Richard Helms ordered the destruction of all MK-Ultra files in 1973. A cache of 20,000 documents survived because they had been misfiled in a financial records building, and were discovered during a 1977 Freedom of Information Act request.This ride borrows the name as a nod to the Upper Peninsula’s own history of isolation and endurance — and to route creator Mark Kransz, whose initials gave the ride its name. 100 miles of gravel through remote forest roads will test your mental fortitude. No mind control required — just legs and grit.Grinduro FormatThis isn't a time trial.
