Chambers Bay 2026

Twilight at the Bay is an evening running event at Chambers Bay in University Place, Washington, offering 5K, 10K, and half marathon distances. The event is timed to start during summer twilight, meaning participants run the course as the sun sets over Puget Sound. The route follows the wide paved Chambers Bay loop trail, featuring flat sections, climbs, and switchbacks, differing from a simple road out-and-back. The 5K covers one loop, the 10K covers two, and the half marathon uses a single longer loop. The primary attraction is the bay views, with the location gaining additional recognition from having hosted the U.S. Open in golf.
