Seattle Marathon: Summer Events

The Seattle Marathon: Summer Events, set for June 27, 2026, in beautiful Seattle, WA, offers runners a chance to experience the Emerald City's charm across 13.1M (Half Marathon), 10K, and 5K distances. This popular, family-friendly event welcomes participants of all levels to enjoy a memorable race day. Typical race day conditions in late June bring pleasant weather, with highs around 74°F and lows around 56°F, and only a 3% chance of precipitation, creating ideal running temperatures.

The courses begin and end at scenic Seward Park, promising iconic views of Lake Washington and, on clear days, the majestic Mount Rainier. While some segments are described as "fast & flat out and back", runners should anticipate rolling hills and changes in elevation throughout the routes. A notable feature for the summer event includes a potentially steep hill early on for some distances. The atmosphere is always lively, with ample support along the course. Aid stations are well-placed, typically every 1.5 to 2 miles, supplying water, electrolyte-replacement drinks, and sometimes energy gels, backed by enthusiastic volunteers providing crucial hydration and encouragement. Dogs are also welcome to join in the fun.

Beyond the personal challenge, the Seattle Marathon: Summer Events creates lasting memories with a vibrant post-race celebration and a commemorative medal for all finishers. For competitive runners, cash prizes are awarded to the top three overall male, female, and non-binary participants in the 5K, 10K, and Half Marathon, provided they meet specific time cutoffs. This annual series also proudly benefits the Jett Foundation's Camp Promise – West and Jett Giving Fund.
