Welcome to the oldest, continuous running triathlon in the world.

Since 1983 triathletes have traveled to Bonelli Park, on the eastern edge of Los Angeles County, to learn the sport; to shake off the winter rust and get ready for the upcoming season; to see old friends and make new friends; and to be in the midst of a fun, high-energy, multi-sport setting. The LA Tri-Series events accomplish all of that and more! If you are new to the sport of triathlon this is the perfect setting to learn open water swimming in a safe environment, cycling around as a safe course with little traffic, and a well-supported run to one of the most beautiful finish lines you will experience. If you are an experienced triathlete who has been waiting for a warm water swim and safe bike course to start off the season, this is for you also.

Come on out and be a part of history at the 42st consecutive LA Tri-Series event.
