Course Information

The route will run between Horsetooth Mountain Park and the Devil’s Backbone Open Space. The majority of the trail is single track with a variety of terrain ranging from smooth dirt paths to very technical rocky sections. A small portion of the route will be on smooth dirt road and gravel bike path.

Aid Stations

There will be four aid stations located along the half marathon course and eight along the marathon course. All aid stations will have water, Succeed! Ultra drink mix, and S! Caps

The Towers Rd aid station and Blue Sky aid station will be minimally stocked with water, Succeed! Ultra drink, S! Caps, and first aid supplies.

The Start/Finish, Indian Summer North, and Indian Summer South aid stations will have water, Succeed! Ultra drink, S! Caps, and a variety of sweet and salty snacks (chips, pretzels, fruit, etc.).

All aid stations will be manned with numerous volunteers to assist you with your race.

Course Marking

We will make our best effort to mark the Marathon and Half Marathon courses with brightly colored ribbons. And we will station volunteers at trail junctions wherever possible to assist runners. But all runners are responsible for navigating the course.
