10K races near Lewiston

Lewiston River Miles

Lewiston hosts 4 10K races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Lewiston runners live on the Snake River Greenbelt Trail, the Greenbelt Trail, and the Lewiston Levee Parkway. Locals run out the door, down the road, and across the bridge when they want easy Z2. The elevated river berm keeps the route simple and steady. Seaport Striders gives the scene its backbone after 40 years in the Lewis-Clark valley. The club meets most Mondays at 4:45 p.m. at Chestnut Park in Clarkston for hill repeats. Longer runners start Saturdays at 7:00 a.m., and the regular 3 to 5 mile run/walk starts at 8:00 a.m. Northwest Series - Day 6, Miles for Mimosas 5K - Lindsay Creek, and Thunderhill Showdown 5K Run/Walk give the calendar its anchor races.

Lewiston riding starts on the same river corridor, with the Greenbelt Trail, Snake River Greenbelt Trail, and Lewiston Levee Parkway doing the base-mile work. The Greenbelt Trail runs seven miles one way, and the Lewiston Levee Parkway stretches about 11 miles toward Hell's Gate State Park. The south end feels quieter because the Lewiston Levee Parkway is a bit more isolated at its south end. Cyclists get their climbing from the hills the towns are built into, not from a named pass. The Snake River wind can make intervals out of nothing, and some days the wind hits like a wall. Hell's Canyon Gruel Duathlon and the 2026 Palouse Sprint Triathlon and Duathlon are the local multisport anchors.

Summer gives runners and riders long river miles, hill repeats, and race-day legs. Thunderhill Showdown 5K Run/Walk lands on July 12, 2026, so locals can use early summer for sharpening after a block of base miles. The Greenbelt and Levee stay useful because the river corridor is paved, direct, and easy to measure. The Clarkston side can be busier than the Lewiston side, so locals pick their side by mood. Winter changes the rhythm more than the map. Runners keep using the Greenbelt and Chestnut Park routines, while cyclists lean harder on the paved river routes when conditions let the wheels roll.
