12th Annual Strong Kids Triathlon

For Ages 2-12

The Strong Kids Triathlon is back! Get ready for glory and giggles, fortitude and photo finishes, triumph and training wheels.

Grab your camera. Bring the floaties. Harness your inner cheerleader. This is about to get adorable.

During the Strong Kids Triathlon, young athletes ages 2 to 12 take on our kid-friendly course — swimming, pedaling and running through the finish line, where medals and victory dances await. While our triathletes will be challenged, the goal is fun. Racers will be organized by age, and distances will be age appropriate. Olympic and collegiate athletes will be on hand for high fives and support. Crowds will cheer, hugs will be given and snacks will be served. No experience is necessary, but smiles are required.

Proceeds from the event will help families in need pay for Y programs.

Race Details

Children will race in heats determined by age groups. Each heat will cater to the skill of each child. Children will begin with lap(s) at the pool, continue with lap(s) on their bikes or trikes and finish with a run around the turf field. 


During the swim portion, we will have lifeguards in the water and on deck. Racers who cannot swim or need help in the water will be assisted by lifeguards. Racers may use flotation devices (such as noodles, kick boards or floaties). Distance varies by wave.

  • 5 & younger: width of the shallow end (about 10 meters)
  • 6-7: 1 length (25 meters)
  • 8-9: 2 lengths (50 meters)
  • 10-12: 4 lengths (100 meters)


Our bike course is completely closed to traffic. Racers may use training wheels, kick bikes, etc. Distances are approximate and vary by wave.

The running course loops the turf field. Volunteers will be on the course to help you count laps. On your final lap, turn onto the field and head to the finish line! Distances are approximate and vary by wave.
