Bruce Fordyce (born 3 December 1955 in Hong Kong) is a South African marathon and ultra marathon athlete. He is best known for having won the South African Comrades Marathon a record nine times, of which eight wins were consecutive. He also won the London three years in a row. He is the current world record holder over 50 miles and the former world record holder over 100 km.
In 1977, when Fordyce first ran the Comrades Marathon, he placed 43rd out of 1,678 entries. He placed 14th in 1978, 3rd in 1979, 2nd in 1980, and was the winner for an unprecedented eight consecutive years from 1981 to 1988; he won it again in 1990. No other runner in the history of the Comrades has achieved this feat.
