Course Description

The 10k is an out and back on a relatively flat (for Steamboat!) course with 1 short steep hill as you make your way to the turnaround. The Half Marathon follows the same course as the 10k to begin, heading south on River Road paralleling the Yampa River for a time before turning right and heading uphill through Dakota Ridge. The half marathon course then continues on a rolling hilly road and circles back along River Road with fabulous views of the Steamboat Ski area and the Yampa Valley.

Aid stations will be stocked with water and Tailwind. Although there will be 3 different aid stations on the course, we highly recommend carrying your own hand-held water bottle to reduce waste and for your own hydration, especially for the half marathon. 10k runners will reach an aid station at approximately 2.5 miles and then again at 3.5 miles (after the turnaround). Half marathoners will reach an aid station at 2.5 miles, ~ 5.7 miles and one more at the turnaround on River Road; on the way back to the finish, half marathon runners will pass the first two aid stations again!  Even though there are several opportunities to pick up water at all of these aid stations, the route is very exposed to sun, so strongly recommend bringing your own water carrying device!

We will have port-o-potties at the start but will only have access to 1 on course for the half marathon that you cross at close to the 6 and 9 mile points. Due to the course location and adjacent private property, we cannot provide more. We are sorry for this inconvenience!
