In 490 B.C., the Athenians won a crucial and decisive battle over the forces of King Darius I of Persia, on a plain near the Greek coastal town of Marathon. Upon delivering the important message of their victory, the Greek soldier who came to tell the good news died — he had completed the 26 mile course running and bearing good news, and did it totally unreserved until the moment he died. Today marathons are run all over the world, commemorating that very event 2500 years ago.
