San Diego is a runner’s paradise. The combination of great weather, beautifully laid out harbor, beaches, and lovely running trails — all fairly accessible — makes San Diego one of my top running cities. What’s especially nice is that travelers staying near downtown/airport/convention center have access to some great routes. Some of the best places to run in San Diego, California include numerous options around the harbor, Mission Beach, Balboa Park, and Sunset Cliffs. There are also some areas worth a special trip, such as La Jolla and Torrey Pines. There are also great opportunities for challenging trail running in the mountains to the east.
