The correct famous marathon runner who delivered the Greek victory is Pheidippides. According to ancient Greek legend, Pheidippides was a Greek messenger who ran from the battlefield of Marathon to Athens to deliver the news of the Greek victory over the Persian forces in the Battle of Marathon in 490 BCE.
Legend has it that Pheidippides ran approximately 26 miles (42 kilometers) without stopping to bring the news of the victory. Upon reaching Athens, he exclaimed "Nenikēkamen" (meaning "We have won" in Greek) and then collapsed and died due to exhaustion.
Pheidippides' legendary run is often cited as the inspiration behind the modern marathon race, which is now a popular long-distance running event held in numerous cities around the world.
