Course & terrain
The San Diego Marathon is a coastal city loop starting and finishing in Balboa Park, passing Mission Bay, SeaWorld, and La Jolla with Pacific Ocean views throughout. The bayfront and coastal flats are the easiest because the terrain stays mostly level, while the short rises around La Jolla and the more exposed coastal roads are tougher when the breeze builds. Spectator support is strongest in Balboa Park, around Mission Bay, and along the La Jolla finish approach.
The San Diego Marathon course is net downhill over 42.195 km (26.2 miles). Runners cover 247 metres of climbing and 318 metres of descent, with a net descent of 71 metres from start to finish.
