SEATTLE, Oct. 22, 2026 — RunX Seattle today announced its inaugural half marathon, taking runners through downtown Seattle on Sunday, June 13, 2027. Registration is now open at runxseattle.com.

‍

The half marathon is the centerpiece of RunX Seattle’s new summer race weekend. Built around the belief that “no two cities run the same,” the event will pair a half marathon through Seattle’s downtown core with opportunities to explore the many sides of the Emerald City’s vibrant culture. Additional weekend programming will be announced as it is confirmed.

‍

“Every neighborhood has its own frequency, shaped by the people, the food, the art, the landscape and what happens on its streets,” said Josh Furlow, CEO of RunX.“Running lets you tune into those frequencies in a unique way. You can seek out something new or return to a favorite neighborhood and notice something you’ve never seen before. That’s the experience we’re building RunX Seattle around.”

‍

RunX Seattle is being developed in partnership with the Seattle Sports Commission, with plans to involve local runners, run clubs, businesses and cultural organizations in experiences leading up to the event and during race weekend.

‍

“With an experienced race production team behind it, RunX will become a flagship summer race weekend for Seattle,” said Beth Knox, President and CEO of the Seattle Sports Commission. “This is an opportunity to establish a new annual tradition that brings residents and visitors downtown. This race is a connection points for participants with Seattle’s diverse neighborhoods, array of local businesses and distinct cultures that make us a world-class city.”

‍

The official map and additional details for the 13.1-mile downtown course will be announced separately.

RunX Seattle welcomes runners preparing for their first half marathon as well as experienced participants looking for their next challenge. Plans also include opportunities for local running communities, businesses and teams to participate together.

“We’re going to build this event in collaboration with Seattle’s runners, businesses and local organizations, and keep building it together year after year,” Furlow said. “That means showing up, asking questions and listening, then bringing what we learn to race day. We want to give people an event they’re proud to have in their city and excited to run again.”
