Age: 24 (Jan. 25, 1951 – May 30, 1975)
Cause of Death: Car accident
Prior to the running boom of the '70s, it was a rare occurrence to see average Joes jogging around the neighborhood block. One of the figures behind that boom (and one of the few who could make running seem badass) was Steve Prefontaine. He set records in several track events ranging from 2,000 to 10,000 meters and won gold at the 1971 Pan American Games. As he prepared for the 1976 Summer Olympics in Montreal, Prefontaine was killed when he lost control of his car just outside of the Oregon University campus.
