Spokane River Run 2026

Our shortest course, the 5K route heads south on double track trail. After approximately 2K the route turns towards the river where some small boulder gardens will require you to pay attention. When you reach the river you’ll follow it back to the start/finish line.

The 10K course winds along single and double track trails for 4-5K, then turns down towards the Spokane River near the "Devils Toenail" rapids, following the river along single track trails all the way back to the finish line.

The 25K course follows the first 4K of the 10K route, but when the 10K turns back, this route heads uphill to the base of the basalt cliffs that Riverside State Park is known for. After climbing the cliffs, the course turns east near an equestrian area and meanders through rolling hills and pine forest before climbing up to a bluff overlooking the Spokane River. You’ll then turn back, dropping down to the river and enjoying great views all the way back to the finish line.

A more difficult 25K, this course is long and difficult! Runners must be able to meet 15 minutes/mile pace. Features significant elevation gain, several technical sections, and a major climb at 16K.
Most of the route is single track but is broken up frequently in the first 10k by sections of double track. The route winds through some of the less-traveled areas of Riverside State Park, passing through a basalt basin dubbed “Craters of the Moon” and climbing from the river at Deep Creek up to the best view on any of our courses. The final 5-6K are a fast downhill finish.

For only the most adventurous, the 50K course combines the 25K and 25K Challenge courses into one beast of a trail run! Runners begin with the 25K Challenge course, facing significant elevation gain from the river all the way to the highest bluff in the park, before descending back to the start/finish area and continuing on the regular 25K course.

Runners may leave a drop bag at the designated area near the start/finish site. This also serves as the mid-point of the race, so drop bags can be accessed at 25k if needed.

Don't miss our Relay Team Name Competition! Every year our volunteer team votes on the best relay team name, with a custom shirt given out to the winning team.

First Leg: 8.75 miles, a longer but somewhat easier leg, with several small hills over mostly rolling single track. Only one water station at mile 4!

Second Leg: 6.75 miles, a shorter but quite difficult leg, with significant hills and a section of technical, rocky terrain.

Third Leg: 8.25 miles, another challenging leg, with a significant climb and a long rocky section of trail.

Fourth Leg: 7.25 miles, the easiest leg, lots of rolling single track and a few moderate hills.

Back after a great debut in 2025! The 25K Tag Team is a two-person relay on the standard 25K course. The first leg runs 8.25 miles and the second runs 7.25 miles, transitioning near the Centennial Trail's Military Cemetery Trailhead.
