It all began in San Diego in 1998 and for over 20 years, the Rock ‘n’ Roll Marathon Series has made running fun by infusing each course with live bands, cheer teams and more. In 2018, we brought our best to the Rock ‘n’ Roll San Diego Marathon & 1/2 with more music, runner support, and community engagement every step of the way. This event has always been our Epic Summer Run, and we’re already planning on ways to make 2019 even better! This year our event will feature a Full (26.2 miles) and 1/2 (13.1 miles) Marathon, a fun 5k Race and a 1/2 Marathon Relay Race. 

The world’s top professional female surfers are back in Oceanside, CA for the 12th Supergirl Surf Pro, a 3-day event July 26-28, 2019.

Over 20,000 gray whales migrate annually from the summer feeding grounds in the Bering Sea, to the winter grounds of the Baja California lagoons, and back again, along the Southern California coast.

San Diego horse racing takes place where the "turf meets the surf" at the Del Mar Racetrack. Fans flock to the track each summer to wager on their favorite horses during the popular, annual Del Mar Thoroughbred Club racing season, mid-July - early-September. Be part of the magic and nostalgia of this long-time horse race tradition dating back to 1937 when Bing Crosby greeted the first guests, and Seabiscuit won by a nose in the infamous race in 1938. This season features the nation's top race horses, trainers and jockeys, and plenty of fun in the sun.

The races run five days weekly, except Monday and Tuesday.

Horse racing at Del Mar happens Wednesday through Sunday, with post time for the first race on most days at 2:00 PM. On Fridays first post is 4:00 PM.
