This flat and fast course is on the roads and paved paths along the Columbia River in all three cities, with the start/finish line at the Lampson Pits in Columbia Park.
Participants will start heading west along Columbia Park Trail in Kennewick and will then turn north on the Sacajawea Heritage Trail to head into Richland. After going under the I-182 Bridge, the course continues north on the Riverfront Trail path until a turnaround point in Howard Amon park. After completing the out & back section, participants will cross the bridge into Pasco and head east on Court Street until turning onto the Sacajawea Heritage Trail and entering Chiawana Park. The course will continue east, passing the Blue Bridge, and will then turn left onto 9th Avenue, where participants will loop around and cross the river on the east side of the Cable Bridge. Once reaching the Kennewick side of the river, the course will head west on the the Sacajawea Heritage Trail until participants turn onto Clover Island for a short out and back. After turning back onto the Sacajawea Heritage Trail westbound, participants will head back into Columbia Park, and wind back around to finish where the race started.
The course elevation varies between 350 and 400 feet above sea level with the total elevation gain being under 410 feet. Most, if not all, of the elevation gain is encountered when going over the river on the bridges so be prepared for these short climbs.
The course will not be closed so please be considerate to other trail users. Announce when you will be passing someone, stay to the right when you are not passing, and make sure to say hi to folks you see - especially the volunteers! Cyclists will be leading the front runners throughout the race and we will have a group of folks sweeping the course after the last person.
The relay option will start and finish at the same location, and follow the same course, as the individual marathon. There will be four unequal legs where the lengths are 8.1, 7.6, 4.0, and 6.5 miles and the transition points are located at the Bradley Blvd parking lot in Richland (46.267454, -119.260886), at the NW parking lot of Chiawana Park in Pasco (46.247861, -119.216043), and near the Road 39 parking lot in Pasco (46.230559, -119.143382).
The half marathon and 5k courses will both start and finish at the same location as the marathon but will be out and back routes with the turnaround located at the halfway point.
