2024 GTIS HALF
ABOUT

Part of the Colorado Mountain Half + Series, Georgetown to Idaho Springs Half is a Colorado Runner’s Must-Do.
Because of its location, this Half Marathon is one of the most pleasurable races in the western US. The point-to-point course is run along Clear Creek and is a scenic and gently rolling mountain course that winds down the Clear Creek Valley. The course runs along the frontage road that runs parallel to, but well away from I-70. Vehicular traffic on the course is normally minimal, however be aware that the road is not closed to traffic. Runners must stay to the right of the yellow lane line.
 

The elevation at the start is 8,500 feet, and gradually arrives at 7,500 feet at the finish. Temperatures in the early morning at this elevation can be 50°, and can reach 85° by the finish. While conditions are usually optimal at this time of year, athletes should always be prepared for adverse weather while being in a mountainous location.
 

For 45 years, the GTIS Half Marathon event has been supporting the Clear Creek Booster Club; a group of parents and community members that supports Clear Creek High School and Clear Creek Middle School in a variety of ways, not just sports.
