Lace up for the Green River Half Marathon and Double Half (Full) on February 7, 2026, a truly unique and community-focused running experience in Kent, WA. This low-key event, known for its friendly atmosphere, welcomes runners to tackle 13.1 or 26.2 miles along the scenic, paved Green River Trail. The course is celebrated for being "super flat," offering an excellent opportunity for a personal best amidst picturesque views of the Green River. Typical race day conditions in early February present cool weather, with highs around 48°F and lows near 38°F, and only a 20% chance of precipitation, making for ideal running temperatures.

Starting and finishing at Three Friends Fishing Hole (19970 Russell Rd, Kent, WA 98032), the race features an out-and-back format. Half marathoners will complete two out-and-back segments, while full marathoners will run four, heading south along the trail for 3.28 miles before returning to the start area for each segment. Aid stations are strategically placed approximately every 6.55 miles, providing water, Gatorade, and a variety of snacks including chips, rice crispy bars, and protein bars. Runners are encouraged to bring their own hydration bottles, as cups may not be provided. While the immediate start/finish restrooms may be closed, alternative facilities are available about 1.5 miles south of the start.

What truly sets this race apart is its grassroots nature; it's a free run with complimentary aid, organized by volunteers, fostering a genuine sense of camaraderie. While there's no entry fee, a suggested donation often benefits local charities like Northwest Harvest. Participants appreciate the uncrowded course and the supportive environment. For those seeking an informal, enjoyable run on a fast course without the typical race day hustle, the Green River Half Marathon and Double Half promises a memorable outing.
