The Big Sur International Marathon is one of the most visually striking road races in the world, held each spring along the rugged coastline of California’s Highway 1. Starting in Big Sur and finishing near Carmel, the race takes place on a closed stretch of Pacific Coast Highway, offering uninterrupted ocean views and a dramatic landscape that few other marathons can match.

The course is point-to-point, running north along the cliffs and headlands of the Central California coast. Runners are treated to sweeping views of the Pacific Ocean on one side and forested hills on the other. The terrain is undulating, with multiple long climbs and descents - including the famously steep Hurricane Point around halfway. While the surface is smooth and the roads are wide, the elevation profile makes this a challenging test for even experienced marathoners.

Weather in late April is usually cool and breezy, with temperatures ranging from 8–14°C and a likelihood of coastal fog or light wind. These conditions are generally favourable for distance running, although wind exposure along the ocean-facing sections can affect pacing.

While not built for personal bests, the Big Sur International Marathon holds strong appeal for serious runners looking for a unique and memorable race experience. Its relatively low sub-3 rate reflects the course difficulty, not the calibre of athletes it attracts. Many club runners target Big Sur as a scenic alternative to traditional urban marathons, drawn by the landscape and the prestige of finishing one of the most iconic races in the United States.

Support along the route includes regular aid stations and enthusiastic volunteers, but crowd support is minimal due to limited access along the highway. The atmosphere is serene and immersive, with the natural environment taking centre stage.

For sub-3 marathoners seeking beauty over speed, the Big Sur International Marathon is hard to beat. It’s a course that demands respect, but rewards those who embrace the hills and run with patience.
