“A Peloton of One” is a new documentary about surviving and healing from childhood sexual abuse, and it is both powerfully moving and enraging. The film centers on a heterosexual male survivor, Dave Ohlmuller, who was abused at age twelve by a priest at his family’s church. Dave is resistant to psychotherapy but has been using exercise and fitness to improve his quality of life and has found his groove in bicycling. He decides to embark on a 700-mile bicycle trip from Chicago to New York, to try to meet other survivors and to raise awareness of the issue. Hence the “Peloton” in the title, which refers to the main pack of riders in a cycle race, who ride close to others to save energy by reducing the drag from the wind.
