The 50K course has been modified for 2025 due to Washington State Parks’ 340-acre forest health treatment project in the area between Seven Mile Road and Carlson Road. Trailhead and trail closures will be in place throughout the project area. The course has been adjusted to ensure safety and a high-quality race experience while avoiding impacted zones.
COURSE OVERVIEW:
The 50K course is a single figure-8 style loop made up of two distinct 25K routes. Runners will complete the first loop—also the 25K Challenge course—then pass through the Start/Finish area before continuing on the second loop, which follows the regular 25K course.
The first loop is the more demanding of the two, featuring roughly 2,200 feet of elevation gain, several technical sections, and mostly single-track trail. It winds through some of the most remote areas of Riverside State Park, crosses the Deep Creek riverbed three times, and climbs to the park’s highest bluff with some of the best views on the course.
The second loop begins with a climb to the base of the iconic basalt cliffs before continuing through pine forest and rolling hills near the equestrian area. After ascending to a scenic bluff above the Spokane River, runners will descend along the river with sweeping views all the way to the finish.
IMPORTANT NOTES:
Do not cross through the Start/Finish line a second time after completing the first loop—this may invalidate your time.
There is a cut-off time of 11:45 AM at the 25K checkpoint in order to continue on with course support.
To see the full 50K route, runners will need to combine both 25K Challenge and 25k course maps.
