Marathon in ancient Greece, the scene of a victory over the Persians in 490 bc; the modern marathon race (strictly one of 26 miles 38 yards or 42.195 km.) is based on the tradition that a messenger ran from Marathon to Athens (22 miles) with the news, dying with the words ‘Greetings, we win!’ on his arrival.
