4th Annual OB Marathon

This is a free, unsanctioned group run organized by the OB Run Club along Ocean Beach and Sunset Cliffs in San Diego. The event uses a course divided into four mapped sections and will have four aid stations. The full distance option listed is the standard marathon length of 26.2 miles; other distance options are available, including a casual 10-mile option and a single-mile participation option. Every participant who runs at least one mile receives a participant sticker. Runners who complete the full 26.2 miles receive special awards.

The course map is presented in four sections and the full route will be posted on Strava starting July 4th. The run concludes with post-run drinks and a potluck at California Wild Ales, 4896 Newport Avenue, San Diego 92107. Because the event is unsanctioned, each runner is responsible for personal safety and for following traffic and pedestrian laws while on the course.
