About the event

Tri the Rock Youth Triathlon
Come for a day of fun, food, prizes and sports. This annual youth triathlon is for young athletes of all skill levels, ages 5 to 18 years old. Tri the Rock encourages kids to get out and give it a try.

All you have to do is try!
Just try. That’s the motto local kids should keep in mind as they pull on their swimsuits, dust off their bikes and lace up their sneakers. It’s time for the Town’s annual Tri the Rock youth triathlon.

Youth athletes of all ability levels, ages 5 to 18, are invited to participate. Registration is available at CRgov.com/TriTheRock.

The race distances are:
Ages 5-6: 25-meter swim (one pool length), 1-kilometer bike ride (one lap around Butterfield Park) and a 500-meter run
Ages 7-10: 50-meter swim (two pool lengths, down and back), 4-kilometer bike ride and a 1-kilometer run
Ages 11-14: 100-meter swim (four pool lengths, down and back twice), 8-kilometer bike ride and a 2-kilometer run
Ages 15-18: 200-meter swim (eight pool lengths, down and back four times), 16-kilometer bike ride and 3-mile run

The registration deadline is 10 p.m. Monday, Sept. 2, and day-of registration will not be offered. Registration fees include a T-shirt, goody bag and post-race meal.

Learn the ins and outs of Tri the Rock and race day protocol at our free informational clinic on Sunday, Aug. 31. Registration required.
