The First Modern Triathlon ™ Series
Half a century ago, on September 25, 1974, at 5:45 p.m., a new kind of race unfolded on Fiesta Island. That evening, forty-six athletes lined up for a 5.3-mile run, a 5-mile bike ride, and a 600-yard swim. The sequence — run, bike, swim — was conceived and directed by Don Shanahan, a Marine, attorney, and lifelong runner who first proposed the idea to the San Diego Track Club.Training Planners, Logs & Journals
