San Diego is one of the best running cities in the United States — 70 miles of coastline, year-round 70-degree weather, and a race calendar that stretches from January through December. Whether you’re chasing a Boston qualifying time, running your first 5K, or looking for a scenic destination race, this guide covers every major race in San Diego County.
Why San Diego Is a Top Running Destination
Few cities offer the variety San Diego delivers. You can race along the Pacific in Pacific Beach, climb the scenic inclines of La Jolla, circle Mission Bay, run through Balboa Park’s Spanish Colonial architecture, or cross the iconic Coronado Bridge. The climate — dry, mild, and predictable — makes San Diego ideal for course PRs and destination-race travel. Most races offer flat to rolling courses with ocean views for much of the route.

Best Time of Year to Race in San Diego
San Diego hosts races year-round, but spring (March–June) and fall (September–November) are peak race seasons with the widest selection of events. Summer races typically start early to beat the heat, while winter hosts holiday-themed runs and half marathons in ideal 55–65°F conditions.
Planning Your San Diego Race Weekend
Most major San Diego races sell out weeks in advance. Register early, book accommodation near your start line (Gaslamp, Pacific Beach, or La Jolla are popular), and arrive a day early to acclimate. The city is runner-friendly with plenty of shakeout-run options along the coast.
