The first modern triathlon did not emerge in isolation. It grew from a decade of transformation in which road racing expanded, masters athletes redefined competition across a lifetime, women and young athletes gained greater visibility, and volunteer-led events opened endurance sports to an entirely new community.Between 1971 and 1979, athletes and organizers throughout San Diego experimented with new distances, formats, and combinations of running, swimming, and cycling. Along the shores of Mission Bay and Fiesta Island, that culture of participation and invention created the conditions from which modern triathlon emerged.The Golden Age of Endurance presents the larger history surrounding the 1974 race—the people, events, and ideas that helped change endurance sports within a single decade.Wednesday September 25, 1974 at 5:45 pm, 46 runners became the world's first triathletes on Fiesta Island.

About the Stories
Hidden in Plain Sightand The First Triathlon Course are unlike any other work on triathlon. They are at once a history, a biography, and a study in endurance, a vivid chronicle of the sport’s evolution from Don Shanahan and Jack Johnstone’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 these book trulys distinctive is their 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. Hidden in Plain Sight’s 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.
The First Triathlon Course is a story narrative from interviews with the Johnstone family, along with records, newsletters, and materials that have been preserved over time. These sources allow a continuous storied experience in the life of Jack Johnstone, teacher, family man, designer of the first triathlon course.

"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 Babbit, Co-founder, Challenged Athletes Foundation & Competitor Magazine - IRONMAN (R) & USA Triathlon (R) Hall of Famer, Media Host/Author
