The name Marathon dates back to the origin of the Florida East Coast Railroad. The name came about by the railroad workers who were working night and day to complete the railway ? due to the unrelenting pace and struggle to complete the project, many of the workers complained that "this [the project] is getting to be a real Marathon", and was later used to name the local station along the railroad
