Tri the Rock event banner

All you need to do is TRI

Tri the Rock inspires kids to get active, help others and try their personal best. Each year, hundreds of kids swim, bike and run through The Meadows neighborhood for this fun and challenging event. Young athletes cross the finish line to the cheers of family and friends and earn the pride of a gleaming medal. 

This year's 14th annual race is Sunday, May 19, from 8 a.m. to noon at Butterfield Crossing Park and Pool, 3952 W. Butterfield Crossing Drive.

Young athletes ages 5 to 14, of all ability levels are invited. 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
Don't delay! The registration deadline is 10 a.m. on Friday, May 17. The local school with the most participants will get to display the traveling Tri the Rock Trophy for an entire year. The registration fee includes a T-shirt, goody bag and event meal. 

Bike racks open at 6:30 a.m. The race begins at 8 a.m. However, check-in for ages 5-6 does not begin until 10:30 a.m., since the group doesn’t start until the other races have finished. Pre-race check-in is available from noon to 2 p.m. Saturday, May 18, at the Castle Rock Recreation Center, 2301 Woodlands Blvd.

Please note, due to road construction around Butterfield Crossing Park, it is recommended to arrive early on race day in order to park.

If you are a Meadows resident, please use extra caution on Sunday when driving in the area of Meadows Boulevard and Butterfield Crossing. The Town’s youngest athletes will be pedaling fast, down Butterfield Crossing, North Meadows and Meadows boulevards.  
Though the Parks and Recreation Department has taken the appropriate steps to ensure the safety of the racers, we ask that community residents be mindful.
