A fun, beginner-friendly youth triathlon at The Plex with swim, bike, and run in a safe, supportive environment.

Get ready for a fun, high-energy day at The Plex Athletic Club Youth Triathlon 2026. Designed for kids ages 4–13, this event offers a supportive and confidence-building race experience for all skill levels. Whether it’s their first triathlon or they’re returning, participants will complete a swim, bike, and run course tailored to their age group.
Race day is structured to be smooth and easy to follow, with waves beginning at 8:00 AM for ages 11–13 and continuing every 45 minutes. A group warm-up before each wave helps athletes feel prepared and ready to go, while our team provides full course support throughout the event.
Every participant will receive a race T-shirt (sizes available while supplies last), finisher medal, race bib, wristband, and race-day swag, along with hydration support and post-race snacks.
We’re also excited to offer a Family Fun Wave, where families can participate together in a relaxed, non-competitive format. Registration opens June 1st and requires a minimum of two participants, including at least one parent or guardian (18+).
After the race, stick around to enjoy vendor booths and activations, sponsor giveaways, post-race snacks, and a fun, family-friendly atmosphere.
Spots are limited and expected to fill quickly, so we encourage registering early to secure your child’s place.
