Runner (soldier) Runner (soldier) A runner was a military courier, a foot soldier responsible for carrying messages during war. Runners were very important to military communications, before telecommunications became commonplace. The Ancient Greek semi-historical character of Pheidippides is said to have been the runner bringing the news of the Greek victory over the Persians from Marathon to Athens in 490 BC. Even though field telephones were widely used for the first time during World War I (1914–18), they relied on copper wire lines, which were often damaged or unreliable. Radio technology existed, but was generally regarded as too insecure for frontline use.
Lake Marathon Lake Marathon Lake Marathon or the Marathon Reservoir (Greek: "Λίμνη Μαραθώνος" ["Limni Marathónos"] or "Λίμνη Μαραθώνα" ["Limni Marathóna"]) is a water supply reservoir formed from the construction of Marathon Dam at the junction of Charadros and Varnavas Torrents near the town of Marathon, Greece. It was the primary water supply for Athens from 1931, when it became operational, until 1959. In 1959 water from Lake Yliki became available, and water from Mornos Reservoir became available in 1981. The area of the lake at the height of the spillway of the dam is 2.45 square kilometres, the maximum depth is 54
