2025 West Side YMCA Kids Triathlon

Get ready for an exciting morning of swim, bike, and run at the West Side YMCA’s Kids Triathlon on Saturday, June 28, 2025!

This fun and supportive event is designed for kids of all fitness levels. Children will receive a race bib to decorate and wear during the race, and every finisher will go home with a medal and a t-shirt. (Please note: t-shirts are guaranteed only for registrations received before June 1.)

The Kids Triathlon features two age divisions:

» Mighty Mites (Ages 6 & Under): 20-yard swim (3'2" deep, flotation devices allowed), 0.5-mile bike ride, 1/4-mile run.

» Junior (Ages 12 & Under): 50-yard swim (5'6" deep, flotation devices allowed), 1.5-mile bike ride, 0.5-mile run.

The course is designed with safety in mind and is subject to change based on weather or conditions. All proceeds from this event support the Y’s Annual Campaign, helping more kids and families access life-changing programs at the Y.

Join us for a day of encouragement, movement, and community at the West Side YMCA!
