Rock 'n' Roll San Diego Marathon

The Rock 'n' Roll San Diego Marathon is an annual marathon foot-race held in San Diego, California. It was established in 1998 and has been run every year since. It is the original race in the Rock 'n' Roll Marathon Series of marathons and half-marathons managed by Competitor Group, Inc.. A half marathon race over 21.0975 kilometres (13.1094 mi) was added to supplement the established full marathon race from the 2010 edition onwards.

The marathon originally commenced at 6th Avenue at Palm and concluded at Parade Deck in Marine Corps Recruit Depot. In 2010 a new course was defined which ended at Sea World San Diego. In 2013, the course was again rerouted with a new finish line at Petco Park. Runners have seven hours in which to complete the marathon. There is also a half-marathon over portions of the same course, and a four-person relay option with a four-hour time limit. Since its inception, the marathon claims to have raised in excess of $100 million for charities (but see below). The 2006 marathon had 21,159 participants—17,339 of whom successfully finished the race.
