The T-Rex Triathlon Series is back again, and the Pterodactyl Triathlon & Duathlon will be held on Wednesday, July 24th. This night race series follows a friendly trail located in the picturesque Island Lake Recreation Area. Each race starts at 6:00 pm. For the first time, each race offers a duathlon option. This means you can choose one of the activities or all four!

The Triathlon kicks off with a .5-mile swim on Kent Lake. You’ll then hit the paved course for a 12.4-mile bike and a 5K run. The duathlon distances are a 1.5-mile run, a 12.4-mile bike, and a 5K run.

Along the way you’ll be able to spot prehistoric creatures.

Races will sell out so make sure to sign up early!
