2018 Strong Kids Triathlon

Presented by Boulder Community Health

Glory. Grit. Giggles.

The YMCA’s Strong Kids Triathlon is part race, part family festival and part exhibition of childhood energy and elation. Oh yes, bring your cameras, because this is about to get adorable. 

During the Strong Kids Triathlon, children take on our kid-friendly course — swimming, pedaling and running through the finish line. There, they will be presented a much-deserved medal by local Olympians (yeah, we know a guy). Crowds will cheer, hugs will be given and snacks will be served. No experience is necessary, but fun is required. Proceeds from the event will benefit the Community Support Campaign for those who need assistance paying for Y programs. For ages 2-15.

We are sold out! We will not accept day of registrations.

July 21, 2018, 9:00am, Arapahoe Y

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)
  • 10-11: 4 lengths (100 meters)
  • 12 & older: 6 lengths (150 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.

Check out more photos from last year’s event. We took LOTS of photos. So many, in fact, that we couldn't fit them all in one Facebook album.
