Bart Yasso

Bart Yasso is an American long-distance runner, born in December 1955 in Fountain Hill, Pennsylvania, who became widely known as the mayor of running while serving as Runner's World magazine's Chief Running Officer. He is one of a few people to have completed races on all seven continents, including the Mount Kilimanjaro marathon, and he won the 1987 U.S. National Biathlon Long Course Championship. By the time he retired he had run in more than 1,200 of the roughly 1,800 races he attended, at distances from one mile up to 146 miles. Among marathon trainers his name is attached to the Yasso 800s workout, believed to indicate a marathon goal time, and his book Race Everything collects some of his favorite races. He is a member of the Running USA Hall of Champions for his accomplishments and his work promoting the sport.
