The word Marathon comes from the name of a city. The legend states that Pheidippides, a Greek messenger, ran the 40 kilometers to Athens from the battlefield of Marathon to announce that the Persians had been defeated in the Battle of Marathon. ① It would be more than 2,000 years before the marathon would make its return, at the revival of the modern Olympic Games in Greece in 1896. ② In that event, 17 runners ran 40 km. ③ Inspired by the event’s success, Boston inaugurated its race the next year; it is now the oldest annual marathon in the world. ④ In 1908, the marathon course at the London Olympics ran from Windsor Castle to the royal box at the Olympic stadium. ⑤ Since the modern games were founded, it has become a tradition for the men’s Olympic marathon to be the last event of the athletics calendar. The length of the race continued varying for years, but in 1924 that specific distance—42,195 meters—was made the worldwide standard.
