The oldest and most historic triathlon series in the United States returns in 2022 for it's 37th running. The LA Tri-Series features courses for all levels of training and competition. Whether you are new triathlon getting started at our Super Sprint; a seasoned triathlon ready to shake off Winter's cold and get back on the course, or looking for a relay with friends - this series is for you.
All LA Tri-Series events feature a flat, safe, and easy open water swim in Puddingstone Reservoir; laps around Frank G. Bonelli Regional Park with all right hand turns, limited traffic and safe roads; a run through the parks trail system to the finish in Picnic Valley.
Become a part of triathlon history, join a great sport and good people and join us at any of the three LA Tri-Series events.
