• 2021 REGISTRATION IS NOW OPEN! WE CANNOT WAIT TO SEE YOU IN PERSON THIS YEAR - THIS EVENT WILL BE CAPPED AT 1,000 TOTAL PARTICIPANTS! Prices for the 2021 GTIS Half will be $75 through 8/13/21 or until we sell out. Sign-up early!


  • COVID MITIGATION: While there will be some changes to our traditional event due to COVID, one thing hasn't changed - the beautiful Colorado scenery! At this time, we anticipate facial coverings will be required in all areas of the event except for while on the race route. Participants will be expected to wear a mask up to the start line, once across the start line, it is at their discretion to remove their mask. We encourage participants to be respectful of those around them, most especially around our amazing volunteers that are out there supporting your efforts!


  • For the start line, this means small groups, socially distanced, will start every 15 minutes beginning at 7:00am. YOU get to select your start time during registration. These times will be strictly adhered to, please plan your arrival accordingly. REGISTER EARLY TO SECURE YOUR START TIME.


  • RUN PERKS: Custom finisher medal, great shirt, fresh mountain air, beautiful scenery, and a fun post-event celebration (on-the-go COVID style finish line celebration).
