The Split Spokane Half Marathon & 5K

Sunday, April 14, 2024 • 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 Split Half Marathon (known as Negative Split before 2020) arrives for its 12th 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 Riverfront Park, Mission Park, and Gonzaga University all the way to the turnaround point across the river from Spokane Community College.

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.
