Walk in
Walk-in registration is available at any HRCA Recreation Center. Walk-in registrations are accepted up to 12:00 p.m. prior to each run day. Please remember that the two adult triathlons do not have race day registration. On the day of each run, you may also register at a higher entry fee. Times and fees for "day of" registrations are listed in the details for each individual race. Highlands Ranch currently has four recreation centers available for your convenience.

Please note: Triathlons usually sell out 3 days prior to the race.

Turkey Day 5K race registrations are different than the HRCA races. See their race pages for registration details.
