The GTIS Half is a Colorado Runner's "Must-Do!" Enjoy a breathtaking view along Clear Creek as you traverse a scenic and gently rolling mountain course that winds down the Clear Creek Valley. The course is a mix of trail, asphalt, road, and cement.
NEW RACE ROUTE: View our new course for 2022 here: https://www.plotaroute.com/route/1872825?units=miles.
Please note: the map is a guide. The course will be measured when set.
There are a number of viewing areas along the course. The start will let you see your runner or walker get off and then they come back at the end of the second mile to the starting area. This allows you see the participants at least twice.
At exit 232 Highway 40 and Empire there is a large area to park on the north side of the frontage road and this is an easy exit to get on and off so you can get to the finish.
Exit 233 Downieville Lawson is a good exit if you take the road back west and meet the runners before they enter the dirt path for open space or as they exit the path by the Animal Shelter.
Your next best place to see the runners would be along Colorado Boulevard in Idaho Springs across the street from Safeway at the park near mile marker 12. Bring your camera there are great shots along the way!
