Course, support, and awards
The Half Marathon is a 6.55-mile out-and-back into Pasco and is USATF certified through 2027. The Marathon follows river trails past the Cable Bridge into Kennewick, continues on trail and bike lanes, and returns to Richland; USATF certification for the Marathon course is in progress. Both courses are mostly flat aside from bridge crossings; the Marathon has about 400 ft of elevation gain and slightly rolling terrain in the final 8 miles. Relay exchanges are located at Road 54 parking in Pasco, the Columbia Park turn in Kennewick, and the east end of Carrier Road in Richland. Aid stations are placed about every 2 miles (about 12 for the Marathon, 6 for the Half), stocked with water, electrolytes, gels, and snacks. All finishers receive a custom finisher medal; top finishers and age-group winners receive special awards. The event requests 70-90 volunteers to support aid stations, marshals, and logistics.
