History

Though the area has been settled for some time, Marathon is a relatively new city, incorporated in 1999.

The name Marathon dates back to the origin of the Florida East Coast Railroad. The name came from the railroad workers who were working night and day to complete the railway; due to the unrelenting pace and struggle to complete the project, workers complained that “this is getting to be a real marathon”, and the word was later used to name the local railroad station.

The Keys historian Dan Gallager in his book Florida’s Great Ocean Railway credits New York playwright Witter Bynner for naming Marathon. According to Gallager, J.R. Parrott, then Florida East Coast Railway’s President and General Manager, invited Brynner to the Keys to “plot stations for the railroad”. When asked to generate a name for the station at Key Vaca, Brynner proposed “Marathon”, inspired by the following passage from Byron: “The mountains look on Marathon—and Marathon looks on the sea.”

Hurricane Irma

Marathon experienced significant damage from the September 10, 2017, U.S. landfall of Hurricane Irma. One of the earliest casualties of the storm was a man who died in a school shelter. Marathon was one of the earliest spots in the Keys to receive transport of needed supplies to deal with the aftermath of Irma. The Air National Guard landed two C-130 transport planes every two hours beginning on the morning of September 11.
