2024 GTIS HALF
COURSE

RACE ROUTE: 
View our course on Plot a Route.
 Please note: the map is a guide. The course will be measured when set. This course is not currently USTAF Certified. 

COURSE DESCRIPTION: 
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 starting at Georgetown Lake, and ends with a slightly challenging uphill as you make your final push to the "one hill of a finish" in Idaho Springs. About 25% of the courses is gravel or dirt, the rest is pavement and cement. Also, the majority of the course is exposed to sun.


Repeat participants might wonder why the course has changed in recent years. The course had to be altered because both Idaho Springs and Georgetown have had significant development over the last few years, including the sale of the former football fields (where the post-event festival was held). This has required applicable municipalities and the event to rework a course that meets all municipalities' requirements for safety.  This new course now takes you around Georgetown Lake and by Bridal Falls, one of the most iconic areas of Idaho Springs.

VIEWING AREAS: 

  1. 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.

  2. 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.

  3. 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.

  4. 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!
