Get ready to hit the trails at the Spokane River Run on April 19, 2026, in beautiful Riverside State Park, Spokane, WA. As one of the Pacific Northwest's oldest and most beloved trail races, this event offers a challenging yet incredibly scenic experience for every level of runner, from a family-friendly 5K to an epic 50K ultramarathon. Choose your adventure from distances including 50K, 25K, 10K, and 5K, with additional options like the demanding 25K Challenge and various relays. Beyond the personal challenge, every stride supports a great cause, as this 100% volunteer-organized race benefits the Garfield Elementary A.P.P.L.E. program and other local community initiatives.

The courses wind through the expansive Riverside State Park, immersing runners in thick pine forests, alongside impressive basalt cliffs, and with breathtaking views of the Spokane River. Expect diverse terrain, primarily single-track trails with some double-track sections, featuring rolling hills and technical segments. The 5K route offers a manageable 57 meters (187 feet) of elevation gain, while the 10K presents a moderately challenging 108 meters (354 feet). For those tackling longer distances, the 25K includes 261 meters (856 feet) of elevation, traversing areas near equestrian trails and offering bluff overlooks. The demanding 50K, a combination of the 25K and 25K Challenge courses, boasts approximately 3,250 feet of elevation gain, taking runners through remote areas, crossing the Deep Creek riverbed, and climbing to the park's highest bluffs for unparalleled vistas.

Runners consistently praise the Spokane River Run for its excellent organization, efficient registration, and well-marked courses. Aid stations are well-stocked with water, HEED sports drink, bananas, and other snacks, with gels available in limited quantities for 25K and 50K participants, who are encouraged to carry their own hydration due to the trails' remote nature. Typical race day conditions in mid-April include comfortable highs around 58°F and lows around 37°F, with a minimal 4% chance of precipitation, making for ideal running weather. All 25K and 50K finishers receive unique "woodals" designed in partnership with local students, and a post-race beer garden adds to the celebratory atmosphere.
