Run through historic neighborhoods including Balboa Park and Old Town. The Marathon, Half Marathon and Relay are packed with live entertainment on course that will keep you rockin’ all the way to the finish line. The Rock ‘n’ Roll Marathon Series is an awesome collection of running events centered on having fun running. Bands, cheerleaders and more fill the courses and thoroughly add the rock and roll to the Rock ‘n’ Roll. The Rock ‘n’ Roll San Diego Marathon is the first of the Rock ‘n’ Roll Marathon series and has been around since 1998. There have been 93 people who have done every single race in SD—I hope I can spot them along the course.
