The course passes the iconic Bixby Bridge at mile 13, McWay Falls viewpoints, and the rugged Big Sur coastline. It is not a personal-best course — the hills and cliffside scenery are the reward.

The Mountains 2 Beach Marathon draws approximately 1,750 finishers each April on a point-to-point road in Ventura, United States. Southern California's premier spring Boston qualifier — a distinct April event from the winter Ventura Marathon, with a spectator-friendly Ojai loop and roughly 700 feet of net descent. The April point-to-point route loops East Ojai at the start, passes Meiners Oaks countryside, the Ventura River basin, the paved Ventura River bike path, downtown Ventura, and a final mile along the Pacific. It is a separate spring race from the February Ventura Marathon (https://www.marathonfocus.com/marathons/ventura-marathon), which uses a shorter Ojai start and the Ojai–Ventura bike path without the opening loop. The route is net downhill overall.
