Marathon is a little city located in the middle of the Florida Keys on the island of Vaca Key towards the north end of the famous Seven Mile Bridge. It has a great view of the lobster traps and sailboats and it still has the charm of a 19th century fishing village. Numerous certified charter boat captains take visitors diving, snorkeling, fishing, sailing and touring along the only living coral reef in North America, several miles offshore in the Atlantic Ocean. Each year, in April, Marathon hosts the annual Seven Mile Bridge Run, with 1,500 runners competing in a foot race over the blue waters of the Atlantic Ocean and Gulf of Mexico. Marathon also has beautiful beaches where you can bring a picnic and the kids can enjoy the playground.
