Lace up for a meaningful stride at the 18th annual Run of Hope Seattle on Sunday, September 20, 2026. This inspiring event, held at the picturesque Seward Park in Seattle, WA, offers a flat and fast course that winds along the scenic southwestern shores of Lake Washington. Runners can choose between a 5K Run or a 3K Walk, with a dedicated 100-yard Kids Dash ensuring fun for the youngest participants. The 5K and 3K courses feature an all-new out-and-back design with a central start and finish line, promising a straightforward and enjoyable experience for all levels. A water station will be available at the 5K turnaround to keep participants hydrated. Typical race day conditions in late September offer mild temperatures, with highs around 70°F and lows around 54°F, and only an 8% chance of precipitation, creating ideal running weather.

Beyond the beautiful setting, the Run of Hope Seattle is a powerful fundraising event dedicated entirely to pediatric cancer research at Seattle Children's Hospital. Since its inception in 2009, the event has raised over $9 million, contributing significantly to breakthrough research. Participants can amplify their impact by supporting specific research funds, including brain tumor research, leukemia and blood disorders research, and solid tumor research. This event fosters a vibrant atmosphere of camaraderie and hope, making every step count towards changing the odds for children facing cancer.

Both the 5K and 3K races are chip-timed, providing accurate results, and medals are awarded to the top three male and female 5K finishers across various age categories. While the course is notably flat, reviews from previous years highlight the immense spirit and turnout, though the popularity of the event can lead to some congestion with walkers on the shared path. Join fellow runners and walkers for a day filled with purpose, community, and the shared goal of advancing pediatric cancer research.
