Tukwila To Alki Half and Full Marathon

Discover the Tukwila To Alki Half and Full Marathon, a distinctive and low-key running event scheduled for January 31, 2026, in Tukwila, WA. This race is celebrated for its minimalist approach, offering a "just-the-basics" experience for those who run for the pure love of the sport, often described as a run "amongst friends". While the name suggests a journey to Alki, note that the current course, updated for 2025 and 2026, is an out-and-back format starting and finishing at 13400 Interurban Avenue South, Tukwila, WA.

Runners will navigate a fast and flat course along paved trails, primarily following the scenic Green River Trail, free from road crossings. The half marathon consists of two 3.3-mile out-and-back segments, while full marathoners complete four such loops. The clearly marked course and favorable elevation profile make it ideal for chasing personal bests. Aid stations are strategically placed approximately every 3.28 miles, providing hydration and a porta-potty at the turnaround near Cecil Moses Memorial Park. However, participants are strongly encouraged to bring their own water bottles. Typical race day conditions in late January include highs around 48F and lows around 38F, with a 22% chance of precipitation.

True to its community spirit, the Tukwila To Alki Marathon is free to enter, though a $20 donation is greatly encouraged, with proceeds benefiting Northwest Harvest or a local food bank. The start/finish line is easily accessible with ample free parking at the adjacent Park & Ride lot. While there are no porta-potties directly at the start, restrooms are available at nearby businesses just a few blocks away. This event promises a focused, no-frills racing experience, allowing runners to connect with the joy of running in a supportive atmosphere.
