Don Shanahan originated the sequence of triathlon: run, bike, swim.
Jack Johnstone mapped the course and safegaurded its memory.
From Fiesta Island in 1974, the sport has grown into a global phenomenon
Hidden in Plain Sight restores Don Shanahan’s story and sets the record straight:
On September 25, 1974, at 5:45 pm, a new kind of race unfolded on Fiesta Island in San Diego. 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, an attorney, and a lifelong competitive runner who first proposed the idea to the San Diego Track Club.

About the Book
Hidden in Plain Sight is unlike any other work on triathlon. It is at once a history, a biography, and a study in endurance — a vivid chronicle of the sport’s evolution from Don Shanahan’s beginnings and the early multi-sport experiments of the 1970s to The First Triathlon™ in 1974 and triathlon’s Olympic debut in Sydney, Australia, in 2000.
What makes this book truly distinctive is its grounding in firsthand testimony from the originator of that inaugural race. Each chapter explores a different dimension of triathlon — its origins, its scientific foundations, and its social and cultural evolution — ultimately revealing the human story behind the balance of work, life, training, and racing. A special section features an in-depth conversation with Don Shanahan, giving readers the rare opportunity to experience a personal Question-and-Answer session with the man who started it all.
Eyewitness & Legacy
“Jack won countless swimming trophies, yet they stayed in boxes. The only award he ever displayed was the Hall of Fame trophy from Triathlete magazine in 1986.”
— Betty Johnstone, wife of Jack Johnstone, Volunteer at the First Triathlon
“Paying your dues matters. The very first triathlon in 1974 wasn’t free; it cost a dollar. One dollar doesn’t sound like much, but it turned a workout into a race. It meant framework, results, and bragging rights… That first dollar proved it was real.”
— Bob Babbitt, Co-founder, Challenged Athletes Foundation & Competitor Magazine · IRONMAN® & USA Triathlon® Hall of Famer · Media Host / Author
