Spectrum Sports is proud to announce that the world's oldest running tri series, the LA Tri Series, will continue for its 43rd year in October 2025!

This year, we'll be racing on Saturday, October 4th, at the long-standing home of the LA Tri, Bonelli Park. In its 43rd year, the LA Tri Series will feature a singular event weekend as we work to revamp the LA Tri into a full-fledged Triathlon Festival. Event day will include races at the Super Sprint and Championship distances, along with the second year of the Iron Bruin Collegiate Distance—a competition open to all current and aspiring collegiate triathletes and alumni. Whether it's your first tri, you're in the middle of a training cycle, or you just want to get out there and go fast, come join us for the 43rd annual LA Triathlon on October 4th at Bonelli Park!!
