5 Stars from 17 ReviewsThe Big Sur International Marathon is a challenging, point-to-point road course run entirely on California Highway 1. Starting in Big Sur and finishing in Carmel, the race is defined by its scenic views and significant elevation changes. It is widely considered one of the most scenic and difficult marathons in the country, featuring a strictly enforced 6-hour time limit.
The course is run on paved asphalt but presents a technical challenge due to the natural crowning of Highway 1; runners often find the slanted surface of the road as taxing as the hills themselves. The layout is a net-loss course, but the "net" figure is misleading as it contains over 1,654 feet of total elevation gain and 1,949 feet of loss.
The topography is hilly and relentless, with the most significant obstacles concentrated in the first 15 miles.
This is may not be a PR (Personal Record) course for many, but it is one of the "must-do" races in the country. The combination of 13 significant hills, the slanted road surface, and potential 20+ mph headwinds makes it a "bucket list" experience rather than a PR attempt. PR attempts usually fall apart at Hurricane Point or during the final three miles of rolling hills in the Highlands. It is best suited for strong hill runners who prioritize mental toughness and scenery over a specific finishing time.
Don't waste months of training only to run the wrong pace.
