Drivers heading out on Whatcom County roads this Sunday morning should plan for slower travel as the annual Bellingham Bay Marathon takes over portions of the county road network. Whatcom County Public Works issued a notice Friday warning motorists to watch for runners between 6:45 a.m. and noon on Sunday, September 20.
What Drivers Should Expect
The Bellingham Bay Marathon routes runners along a course that uses both city streets and county roads in the Bellingham area, making it one of the more traffic-disruptive local events of the fall calendar. The race begins early, with runners on the course from 6:45 a.m., and the county estimates the last runners will clear county roads by approximately noon.
Whatcom County Public Works has posted a detailed course map for drivers who want to plan alternate routes. The map is available at the shortened link distributed in the county's public notice. Residents who regularly commute or run errands on county roads south and west of Bellingham on Sunday mornings should check the map before heading out, as the race course crosses several road segments that would otherwise carry normal weekend traffic.
Law enforcement and race volunteers will be stationed at key intersections to manage traffic and ensure runner safety. Motorists are asked to slow down significantly in areas where runners are present, yield to participants crossing roadways, and follow the directions of any flaggers or officers on site.
About the Bellingham Bay Marathon
The Bellingham Bay Marathon is one of the Pacific Northwest's most scenic road races, drawing participants from across Washington state and beyond each fall. The event, organized by Bellingham Bay Marathon, typically offers a full marathon, half marathon, and relay options, with routes that wind through neighborhoods and along waterfront and rural road segments that showcase the Whatcom County landscape.
The race has been a fixture on the Bellingham events calendar for years and typically attracts hundreds of runners to downtown Bellingham and surrounding areas the morning of the event. Hotels in the area often see higher weekend occupancy during marathon weekend, and local businesses along the course route tend to have increased foot traffic before and after the race.
Sunday's weather looks cooperative. Whatcom County Emergency Management's Friday briefing noted dry and stable conditions are expected to continue through the weekend, with mainly clear skies and light winds, temperatures near seasonal averages. It is about as good a race-day forecast as organizers could hope for in mid-September.
Planning Ahead if You Are Driving Sunday
If you need to travel on county roads between Bellingham and the surrounding rural areas Sunday morning, the best approach is to check the course map in advance and identify whether your planned route intersects with the race. The window of 6:45 a.m. to noon covers most of the morning, so early risers heading to farmers markets, church, or recreation areas should account for possible delays or detours.
Residents near the course who may see runners passing through their neighborhood should expect increased foot and vehicle traffic from spectators as well. Keeping driveways clear and being alert when backing out are simple steps that help keep the event safe for everyone involved.
The county's public notice links to the full course map at the official race route page, where drivers can zoom in to check specific intersections or road segments. After Sunday noon, all county roads should be fully open to normal traffic flow.
