PHEIDIPPIDES
Pheidippides (sometimes given as Phidippides or Philippides), hero of Ancient Greece, is the central figure in a story which was the inspiration for a modern sporting event, the marathon.
The traditional story relates that Pheidippides (530 BC–490 BC), an Athenian herald, was sent to Sparta to request help when the Persians landed at Marathon, Greece.
He ran 240 km (150 miles) in two days. He then ran the 40 km (25 miles) from the battlefield near the town of Marathon to Athens to announce the Greek victory over Persia in the Battle of Marathon (490 BC) with the word "Nenikékamen" ('We have won') and collapsed and died on the spot because of exhaustion.
Most accounts incorrectly attribute this story to the historian Herodotus, who wrote the history of the Persian Wars in his Histories (composed about 440 BC). In reality, the traditional story appears to be a conflation from several different ancient Greek sources having varying levels of authenticity.
