Defeat Myeloma 5K

Lace up for the inspiring Defeat Myeloma 5K, a family-friendly run/walk set in scenic Seattle, WA, on June 28, 2026. Taking place at Magnuson Park (7400 Sandpoint Way NE), participants can choose between a 5K or a 1-mile distance, with a free Kids Dash also available for the younger enthusiasts. This event offers a unique opportunity to experience a "flat, fast course" with breathtaking views of the water and majestic Mt. Rainier, making for an enjoyable and accessible experience for all ability levels. There's no time limit, ensuring everyone can cross the finish line at their own pace.

The Defeat Myeloma 5K stands out for its profound mission: 100% of all proceeds directly benefit immunotherapy research for multiple myeloma at the Fred Hutch Cancer Research Center. Established in 2013, the event has raised over $1.4 million to date, making a significant impact in the fight against this disease. Runners will find a supportive atmosphere, celebrating survivors and honoring loved ones. Typical race day conditions in late June in Seattle are pleasant, with highs around 74F and lows around 56F, and a minimal 3% chance of precipitation.

Runners can expect a well-supported experience, with a water station conveniently located at the halfway mark of the 5K course, and refreshing water and snacks awaiting at the finish line. The start and finish lines are easily accessible just north of the boat launch within Magnuson Park, with clear signage from the 65th Street entrance guiding participants to parking and the race start. Strollers and leashed, well-behaved dogs are also welcome, further enhancing the community-focused and inclusive nature of this impactful event.
