Marathon is a city in the middle of the Florida Keys, in Monroe County, spread across a roughly ten-mile chain of islands between Key Largo to the northeast and Key West to the southwest. U.S. Highway 1, the Overseas Highway, runs the length of the community, and the Seven Mile Bridge marks its western approach. The city is home to about 9,700 residents. Marathon grew from a fishing and railroad settlement into one of the Keys' principal communities, and its economy remains tied to the water. Commercial and charter fishing, boating, and tourism anchor local life, and the city serves as a hub for the Middle Keys. Its central location makes it a convenient base for exploring the entire island chain. The community is known for a distinctive mix of natural and conservation attractions. Sombrero Beach offers a sandy shoreline for swimming and snorkeling, while The Turtle Hospital operates as a working sea-turtle rescue and rehabilitation center that draws visitors to its educational tours. Crane Point Hammock preserves hardwood hammock, maritime heritage, and nature trails, and the nearby Dolphin Research Center focuses on marine mammal education and care. Marathon offers a relaxed, water-oriented lifestyle. Fishing, diving, snorkeling, and boating are woven into daily life, and the surrounding waters of Florida Bay and the Atlantic provide year-round recreation. Public schools belong to the Monroe County School District, with campuses including Marathon High School and Stanley Switlik Elementary. Marathon appeals to residents and second-home buyers drawn to the Keys' island lifestyle, natural environment, and strong sense of community, and its location places Key West and Key Largo each within an easy drive.
