Due to unsafe water quality test results received Thursday, May 1st, 2025 Cal Tri San Antonio - 5.4.25 has transitioned to a runbikerun format. The safety of our athletes, swim safety team, volunteers, and staff is always our highest priority. We understand how deeply disappointing this is—especially for those who have trained hard for the traditional swimbikerun format. Our team is working diligently to ensure the revised event still provides a challenging, fun, and rewarding experience. We have put multiple options in place for you, including free transfer and deferral:

-SATURDAY’S ATHLETICA SWIM & COACHING CLINIC. While there will be no swim, the clinic will take place with a focus on the bike and run disciplines as well as transition skills.

-REVISED EVENT FORMATS (4 OF 6 EVENTS)
–Triathlon (swimbikerun) replaced by runbikerun. The swim discipline is replaced by a single 1K loop around the lake which prevents crowding in the transition area.
–Swimbike replaced by runbike. The swim discipline is replaced by a single 1K loop around the lake which prevents crowding in the transition area.
–Swimrun replaced by the 5K or 10K only.
–Swim only canceled. This impacts 3 athletes.

-EVENT FORMATS THAT REMAIN THE SAME (2 OF 6 EVENTS)
–Runbikerun
–Run (5K & 10K)
