The Hood to Coast Relay is a unique long-distance relay race held in the U.S. state of Oregon, annually in late August, traditionally on the Friday and Saturday of the weekend before the Labor Day weekend. It is the longest major relay in North America and the largest in the world in terms of total participation (12,000 participants annually). The course runs 197 miles (317 km) from Timberline Lodge on the slopes of Mount Hood, the tallest peak in Oregon, through the Portland metropolitan area, and across the Oregon Coast Range to the city of Seaside on the Oregon Coast. The first relay was held in 1982 and drew eight teams, but due to growth is now limited to 1,000 twelve-person teams. Teams in Hood to Coast must complete the course within a 31 hour time limit (an average of 9 minutes 30 seconds a mile). Walkers and high school teams may choose to compete in the Portland to Coast Walk or Portland to Coast High School Challenge respectively, both of which are held in conjunction with the main relay and start in downtown Portland instead of Mount Hood. Portland to Coast Walk and High School Challenge are limited to 400 and 50 teams respectively; entries are accepted on a first-come-first-served basis until all spaces are filled.
