San Diego Beach & Bay Half Marathon, 5K & 10K

Saturday, April 12, 2025 • San Diego, CA • Course Map

Set for its 7th annual running around the sun-dappled waters of Mission Bay, this half marathon features a fast and very flat course that offers the chance to take in the gorgeous skyline of San Diego and its beaches, and run past some of its best-loved attractions.

You’ll start the race at Tecolote Shores, a beach area that overlooks the bay from just south of the Hilton San Diego Resorts and Spa, along Enchanted Cove. From there, you’ll head south and then west along the roads and trails that run alongside the bay, through South Shores Park and then past SeaWorld San Diego.

After you make it across the bridge at Mission Bay Drive, you’ll head over to Ventura Cove Park and then to the residential areas at Mission Beach Park. That will take you up along the beachfront and past Belmont Park, where you’ll pass the Giant Dipper Roller Coaster along the way.

Later stretches of the race keep you running around the bay, with stretches through Bay View Villas and Riviera Drive, and then through Crown Point Park and later through Mission Bay Park.

All throughout the course, the elevation rises barely register — most of the course lies at about a dozen feet above sea level, and it’s a mixture of paved roads and trails through the parks along the waterfront.

You’ll need to keep a pace of 16 minutes per mile or faster in order to finish the half marathon within the 3 1/2 hour time limit.
