Marathon (Demotic Greek: Μαραθώνας, Marathónas; Attic/Katharevousa: Μαραθών, Marathṓn) is a town in Greece and the site of the Battle of Marathon in 490 BCE, in which the heavily outnumbered Athenian army defeated the Persians. Legend has it that Pheidippides, a Greek herald at the battle, was sent running from Marathon to Athens to announce the victory, which is how the marathon running race was conceived in modern times.[n 1] Today it is part of East Attica regional unit, in the outskirts of Athens and a popular resort town and center of agriculture.
