Magnuson Series - Holiday Fun Run

Lace up your holiday spirit for the Magnuson Series - Holiday Fun Run, taking place on December 19, 2026, in scenic Seattle, WA. This festive event offers distances of 5K, 10K, and 15K, inviting runners of all levels to spread some cheer. The course winds through beautiful Magnuson Park, set along the picturesque shores of Lake Washington, providing a largely flat and fast experience ideal for chasing a personal best or enjoying a leisurely holiday jog. While mostly paved, sections of gravel and grass add variety to the USATF-certified 5K loop, which 10K and 15K participants will complete multiple times. Be mindful of one "good hill" near the end of the first kilometer, offering a manageable challenge.

The Magnuson Series, known for its accessible events and support for local non-profits like Earth Runs, encourages a vibrant, family-friendly atmosphere. Runners are encouraged to don their most festive holiday sweaters and hats, with prizes awarded for the best-dressed participants. Leashed dogs and strollers are welcome, making it a truly inclusive outing. Aid station support is conveniently located at the start/finish line, accessible with each lap, alongside restrooms and Sani-cans along the course.

As you cross the finish line at Magnuson Park, a warm hot chocolate bar awaits to celebrate your achievement and ward off the typical December chill, where highs are usually around 46F and lows near 36F, with a 23% chance of precipitation. Whether you're aiming for a new record or simply soaking in the holiday ambiance, the Magnuson Series - Holiday Fun Run promises a memorable and engaging race experience.
