Note: A virtual option is available for the 2020 half marathon, to be run by December 31, 2020.
Set for its 10th annual running in 2021 alongside other big-name events on the city’s race calendar — including June’s Rock & Roll San Diego Marathon & Half Marathon, the America’s Finest City Half Marathon in August and November’s Silver Strand Half Marathon — the San Diego Half Marathon features an out-and-back course that starts near Petco Park, the home of baseball’s San Diego Padres.
Just over 6,500 runners crossed the finish line in the half marathon and 5K combined in 2016. Located just blocks from Balboa Park, the ballpark looks out onto both downtown San Diego through the outfield, and the San Diego Convention Center, marina and San Diego Bay to the south.
From there, the course will take runners northwest away from the ballpark in the direction of the San Diego Airport and Harbor Island, where they’ll make a loop around the island looking out onto the water and the U.S. Navy ships parked in the harbor.
After the stretch around Harbor Island, runners will make their way next to Liberty Station, where the Spanish Colonial Revival style buildings of the former Naval training station have been turned into a mixed-use entertainment and shopping district with restaurants, theaters and residential neighborhoods.
Once they make it to the turnaround point in Liberty Station, runners will then head back into downtown and back towards the ballpark, leaving the roads that run along the bay for a stretch that takes them through downtown, and then down 5th Avenue for a finish under the Gaslamp Arch.
The starting time for the race is scheduled to begin at 7:30 AM for runners in the half marathon. The race also will be run in conjunction with the Celebrate San Diego festival on the same day, which will be getting underway during the race and should be in full swing by the time runners cross the finish line.
Organizers note that the number of entrants for all the races combined is limited to 8,000. There’s also a half marathon relay for two-person teams, so check the official race website for more info.
