Negative Split Spokane Half Marathon & 5K

Sunday, September 27, 2020 • Spokane, WACourse Map

Named for the running terminology “negative split” — which means running the second half of a race faster than the first half — Spokane’s Negative Split Half Marathon arrives for its 8th annual running this year.

Runners will start the out-and-back loop course for the race in Kendall Yards on Summit Parkway near Cedar Street and a short distance from Spokane’s Riverfront Park, just across the river from Canada Island.

From there, they’ll follow a counter-clockwise loop route largely along the Centennial Trail, a 37 1/2-mile-long paved trail that runs alongside the river and features flat, fast terrain with plentiful tree shade.

The course unfolds along the bends in the river, taking runners past Mission Park, Spokane Community College and John C. Shields Park all the way to the turnaround point at Camp Sekani Park along the river.

There, runners will make the turn and retrace their steps along the Centennial Trail all the way back to the bridge where they crossed the river in the first half of the race.

Instead of crossing back over the river, however, this time they’ll continue on along the northern bank of the river back to Riverfront Park, where the race finish line lies.
