Great Columbia Crossing 10K
The Great Columbia Crossing 10K is a run/walk held in Astoria, Oregon that crosses the Astoria-Megler Bridge from Washington to Oregon during the annual October event. Pedestrians are allowed on the bridge only once each year. The bridge is described as the longest continuous truss bridge in North America.
The course is a 10 kilometer route on a fairly flat road with one steep incline to the peak of the bridge. The event began in 1982 and is typically scheduled on the second Sunday in October.
Distances:
- 10 km in-person on the bridge
- Virtual 10K without bridge access
Registration details for 2026 show that registration opened June 1 and sold out on June 7, with the event reaching capacity at 3,500 participants. Standard registration includes chip timing and was listed at $60 per person, with a listed late fee of $65 if space remained available. Youth under 10 could register free without chip timing. Virtual registration was listed at $50 and includes a T-shirt and shipping. A long-sleeve event T-shirt was offered for $25, with a $5 pre-order discount before July 1.
The event serves as a fundraiser for the Astoria-Warrenton Area Chamber of Commerce. The race issues wooden "Clam Bucks" tokens that function like cash at participating local businesses. Volunteer shifts are scheduled in the days around the event and include perks such as a long-sleeve event T-shirt, Clam Bucks, and entry into a volunteer drawing.
