From early miles along the coast to the final push towards the finish, these events bring together a mix of competitive energy and laid-back Southern California spirit. Expect cool air off the Pacific, stretches through lively neighborhoods, and, at times, unique access through local military bases that add a different perspective to race day.

organization is solid, with frequent aid stations, on-course medical support, and pace groups for a wide range of finish goals. It’s the kind of race environment that makes it easier to focus on your run, whether you’re aiming to qualify for Boston or simply want to complete your first marathon in a setting that’s as welcoming as it is motivating.
