Big Sur International Marathon: Quick Facts

Where Is the Big Sur International Marathon?

The big sur international marathon takes place on California's Central Coast, between Monterey County's Big Sur region and the town of Carmel-by-the-Sea. Runners start near the Big Sur Station and finish at Rio Road in Carmel, covering the entire route on Highway 1, the nation's first officially designated Scenic Highway.

This stretch of coastline sits about two hours south of San Francisco and offers uninterrupted views of the Pacific Ocean, redwood forest, and rugged cliffs for the full 26.2 miles.

When Is the Big Sur Marathon?

The race runs every year on the last Sunday of April. The 2026 event takes place on April 26, and the 2027 race is scheduled for April 25. Organizers close a full stretch of Highway 1 to vehicle traffic for the morning, so the date rarely changes from year to year.

Runners planning to travel should book accommodations early. Hotels in Carmel, Monterey, and Pacific Grove fill up months ahead of race weekend because of limited lodging near the course.For More Detail Visit Official Big Sur International Marathon site.

How Many Miles Is the Big Sur Marathon?

The big sur marathon covers the standard marathon distance of 26.2 miles (42.2 kilometers), run point-to-point from Big Sur to Carmel. The event also offers shorter distances on the same weekend, including a 21-Miler, 12K, 5K, and a marathon relay, so runners of different experience levels can take part.

What Is the Big Sur Marathon Course and Route Like?

The big sur marathon course follows Highway 1 south to north, moving through redwood groves before opening onto sweeping coastal views. The halfway point crosses the Bixby Bridge, where a grand piano typically plays as runners pass. Taiko drummers and other musicians line sections of the route as well.

For the big sur marathon route and map, expect these general segments:

• Miles 1-9: Inland through Big Sur State Park and redwood forest, with rolling hills.
• Miles 10-13: Climb toward the Bixby Bridge, the course's signature landmark and highest point.
• Miles 14-18: Descent along open coastline with strong headwinds possible.
• Miles 19-23: Rolling terrain through Point Lobos and Carmel Highlands.
• Miles 24-26.2: Flatter finish into downtown Carmel.

Official course maps are available on the race organizer's website closer to race day, and runners are encouraged to review the elevation profile before race week.

Big Sur Marathon Elevation: Is the Course Hilly?

Big Sur elevation numbers explain why this race has a reputation as one of the toughest marathons in the country. The course starts at 356 feet and finishes at just 10 feet, but the route is far from a straight descent.

Is the Big Sur Marathon Good for First-Time Runners?

The big sur race is not typically recommended as a first marathon. The hills, six-hour time limit, and limited crowd support in some sections make it more suitable for runners who have already completed at least one marathon. First-time marathoners are better served by a flatter course before attempting Big Sur's climbs and coastal winds.

Runners with prior marathon experience who want a bucket-list race with world-class scenery will find Big Sur a rewarding challenge.

Big Sur International Marathon Registration

Big sur international marathon registration typically opens in the fall for the following April's race, through the official race organizer, the Big Sur Marathon Foundation, a nonprofit that has produced the event since 1986. Demand is high, and the marathon distance often reaches capacity or moves to a lottery system.

Steps for big sur marathon registration: 

1. Check the entry method. Some years use direct registration; others use a random drawing.
2. Register early. Fields for the marathon distance are capped, and entries close once capacity is reached.
3. Choose your distance. Options include the full marathon, 21-Miler, marathon relay, 12K, and 5K.
4. Confirm travel logistics. Book lodging in Carmel or Monterey, since shuttle service to the point-to-point start is required.
5. Review the athlete guide. The Big Sur Marathon Foundation publishes course rules, packet pickup details, and race-day policies before the event.

Big Sur Marathon Results and Tracking

Big sur marathon results and big sur race results are posted on the official results platform after the event, searchable by bib number, name, or finish time. Historical results from past years are also archived for runners who want to check course records or compare finish times.

For big sur international marathon results and live big sur marathon tracking on race day, the race organizer offers a mobile tracking tool that sends split updates at key checkpoints, including the Bixby Bridge halfway mark. Friends and family who cannot attend in person can follow a runner's progress through these live splits.

How to Train for the Big Sur International Marathon

Training for this course means preparing for hills, coastal wind, and a strict time limit. Follow these steps to build race readiness:

1. Build your base mileage first. Spend 8 to 10 weeks increasing weekly mileage gradually before adding hill-specific work.
2. Add hill repeats weekly. Practice both uphill effort and controlled downhill running, since the descent after Bixby Bridge stresses the quads.
3. Train in variable wind conditions when possible. Coastal wind can slow pace significantly in the race's second half.
4. Practice your race-day pace on rolling terrain. Avoid treadmill-only training if you can access hills or trails.
5. Taper properly in the final two weeks. Reduce mileage while keeping some race-pace intensity to stay sharp for race day.

Fueling Strategy for Big Sur

Race-day nutrition matters as much as training on a course with this much elevation change. Runners need a fueling plan that supports both energy output and blood flow to working muscles across more than four hours on the course.

• Dietary nitrate for blood flow. Nitrate, found naturally in beetroot, supports nitric oxide production, which helps widen blood vessels and improve oxygen delivery to working muscles. A narrative review published on PMC found beetroot juice supplementation can improve exercise economy by reducing the oxygen cost of endurance activity.
• Beet juice in your pre-race routine. Many runners take beetroot juice in the days leading up to a marathon.
• Hydration. Stay consistently hydrated in the days before the race, not just the morning of.
• Carbohydrate fueling. Practice your fueling plan during long training runs, not for the first time on race day.
• No new products on race day. Avoid foods or supplements you have not already tested in training.
• Temperature swings. Plan for cooler coastal air at the start and warmer conditions later on the course.

Key Takeaways

• The Big Sur International Marathon runs 26.2 miles from Big Sur to Carmel on the last Sunday of April.
