The Olethros 100 is an annual motor race that is held every September on the Olethros race track in Greece, and was inaugurated in 1955.
The first ever race was held in 1955, won by the legendary Italian driver Daniele 'Dominating Danny' Raimondi.
The first British winner of the race was Francis Alvis Jr. in 1959, when Raimondi crashed out of the race when it looked like he was to add to his tally.
The first local driver to win the race was Vangelis Pattas in 1961, and he would also win in 1962 and 1964, making him the greatest Greek driver of all time.
The most successful driver ever is Greg Eagle who won five times, four in consecutive years between 1994-1997, and one more win in 2000.
