Since 1998, The Rock 'n' Roll San Diego Marathon and Half Marathon is a unique event that combines running with entertainment. Upwards of 30 stages host live music along the course while 2,000 cheerleaders encourage runners to the finish line. The race weekend also includes a two-day Health and Fitness Expo where you'll find the latest in gear, services and apparel. You can also talk to experts in health, nutrition, travel, investment and finance. All racers are required to pick up their race number (photo ID required), timing chip, T- shirt and goodie bag at the sports and fitness expo. The race start line is at Laurel and 6th Avenue on the west end of Balboa Park. The Sports and Fitness Expo is held at the San Diego Convention Center.
