No Relays. Cal Tri Events no longer offers any relay options as the registration process creates excessive administrative burden due to consumer confusion for those events. Currently registered 2024 relay events will proceed however we are no longer taking new relays. Never say never but relays are not being considered in the near future. With swimbike, swimrun, swim and run events there are still ample multisport options.
Athlete Friendly Initiatives. Returning in 2025 are the athlete and family friendly initiatives that are critical to support Cal Tri Events safe, affordable & accessible mission.
