Marathon is a long-distance running event with an official distance of precisely 42.195 kilometers. It was one of the original modern Olympic events in 1896. Its origins go back to Greek mythology commemorating the fabled run of the Greek soldier Pheidippides. He ran from the battlefield of Marathon to Athens to announce that the Persians had been defeated by the Greeks. Today, more than 500 marathons are held throughout the world each year. epa’s sports picture coverage offers a wide variety of marathon photos from around the globe including images from the New York Marathon, the Berlin Marathon, the Boston Marathon and the London Marathon.
