In 2014, an amateur cyclist named Bryan Fogel had an eccentric idea for a film: He had just participated in a prestigious and grueling alpine stage race called the Haute Route in the Alps and had finished in 14th place. He decided to spend the next year not just training, but also doping. He meant to come back and run the race again the following year. He meant to not get caught for the doping. He expected the doping would vault him into the group of elite leaders who had finished above him.
