Sea Island Half Marathon & 5K

Saturday, December 1, 2018 • Sea Island, GA • Course Map

You’ll get your chance to run through one of the East Coast’s most exclusive (and gorgeously scenic) resorts when you run the Sea Island Half Marathon this December, the second annual running of a half marathon that unfolds along the famed Sea Island Drive, where live oaks hang over the roads and perfectly manicured lawns lead up to some of the most luxurious beachfront homes anywhere.

Thanks to its location — Sea Island lies just a few feet above sea level, and it’s the only resort in the world to achieve four Forbes Five-Stars 10 years in a row – the course for the race is pancake-flat for virtually your entire 13.1 miles.

The island is perhaps best-known for the Cloister, its legendary Spanish colonial-style hotel that first opened back in the 1920s and has welcomed famous guests from President Calvin Coolidge and George H.W. Bush to John D. Rockefeller and Eugene O’Neill, who wrote his play “Ah, Wilderness!” while staying on the island.

The hotel today is a five-star resort that got a major renovation a decade ago, and you’ll get to see many of its newer amenities from the course as you run past.

The race begins at Rainbow Island, and from there, half marathoners quickly cross the bridge and head onto Sea Island, heading north along Sea Island Drive for the first half of the race. This section of the race features the picturesque homes that Sea Island is known for (and maybe the most luxurious you’ll ever see). After several miles on Sea Island Drive, the race turns left onto Oglethorpe Drive for another mile or so before retracing the steps of the race and reaching the halfway point.

Then runners head across the bridge again, now officially on Saint Simon’s Island, where they’ll coast south toward the finish line at the Lodge at Sea Island Golf Club.

Like many destination races, the party is just beginning at the finish line; mimosas, craft beer, and brunch prepared by the resort team await finishers. The post-race party goes on until 11:30 AM.

The race includes a 5K distance and will be capped at 1,000 runners, organizers note, and there will be a 3 hour, 15 minute time limit for the half marathon.
