On your marks, get set, go! RunX Seattle is launching its first-ever half marathon on Sunday, June 13, 2027.
The goal of the marathon is to immerse participants in the Emerald City’s vibrant culture and help them experience Seattle in a different way while running its streets.
“RunX is built around a simple idea: no two cities run the same,” event officials said in a news release.
