Marathon is a community located in "the heart of the Florida Keys" just 50 miles from Key West and approximately two hours driving time from Miami. We are primarily a community of family homes with a permanent population of less than 12,500. Our seasonal population increases during the winter months with a second home or condominium owners. Our tropical climate averages 78.50 F year round, with no snow, no frost, but plenty of sunshine!

As you can imagine, we are a water-oriented island with fishing, diving, sailing and water sports, just some of the reasons people move here to live, work and play! Our primary industry is tourism, followed by fishing.

According to local legend, Marathon got its name early this century when we were the base of operations for the construction of Flagler’s Railroad, and the workers referred to the non-stop work schedule as a "marathon". Our history is being well preserved by the local Pigeon Key Foundation as well as by the Museums of Crane Point Hammock, both of which are located in Marathon.
