PORTLAND -- About 17,000 people are expected to run or walk in the annual Hood to Coast relay this weekend and westbound lanes will be closed on highways 26 and 30 during the race.

The route runs from Timberline Lodge to Seaside and drivers are asked watch for runners, walkers and about 3,000 support vehicles that will be following along.

Hood to Coast forecast

The race started Friday at 6:30 a.m. and waves of relay teams will continue to depart until 6:45 p.m. Most teams have 12 people and each team runs 36 legs, covering nearly 200 miles from Mt. Hood to the Oregon coast.

Teams will begin to reach the finish line early Saturday morning and continue arriving throughout the evening.

The relay race, billed as the largest in the world, has become an annual tradition for many runners. The 2013 race marks the 23rd Hood to Coast for Kathy Ryan, who suffered a heart attack during the race a few years ago.

I don't want to be a victim, I want to be a survivor, Ryan told KGW Friday. That's what keeps me going.

One westbound lane of U.S. 26 near milepost 30, east of Sandy, will be closed for support vehicle parking. Westbound lanes will close intermittently on U.S. 30 east of the Sauvie Island Bridge as runners cross the highway at Walnut Street. Drivers should expect delays in the area.
