Initially he was a boxer attached to Kenyan postal service before concentrating on running.[2] He won the Great North Run a record four times; in 1991, 1992, 1994 and 1996. He also won the City-Pier-City Loop half marathon in the Hague twice in 1993 and 1994.[3]
His career as a top runner came to a premature end. The Portsmouth 10 Mile race in 1996 was among his last notable achievements. His reveller lifestyle may have contributed to deteriorating performances.[4]
