Google should not be necessary for these greats, but since you insist:
Suleiman Nyambui (born February 13, 1953) is a former athlete from Tanzania who won the silver medal in 5000 metres at the 1980 Summer Olympics.
He also won a bronze medal at the 1978 All-Africa Games, and twice (1987 and 1988) triumphed at the Berlin Marathon.
Attended the University of Texas at El Paso (UTEP) from 1978 to 1982, where, as an older aged athlete (he was 29 when he graduated), he won four straight NCAA titles in the 10,000 meters — one of only five Division I men to ever accomplish such a feat. He also won 3 straight NCAA titles in the 5,000 meters while at UTEP and was the 1980 NCAA Cross Country champion. In a memorable Millrose Games race in New York in February 1981, Nyambui broke the world indoor 5,000 meter record with a 13:20.4, just head of Alberto Salazar who broke the American indoor 5,000 meter record.
Outdoors, his 5,000 PR was 13:12. With Gidamis Shahanga at UTEP, they were an awesome 1-2 punch.
Nyambui had a low arm carriage that was distinctive and constrasted with the high arm carriage of Juma Ikanga.
Ikanga was perhaps five foot two, maybe five foot three, but competed with the best. He had a huge stride, with high knee lift.
From Google: Juam was a sentimental favorite in Boston after finishing second three years in a row at the Boston Marathon from 1988-1990. A great trainer, Ikangaa said "The will to win means nothing without the will to prepare." He allegedly ran over 200 miles per week for ten years straight. His achievements:
2:08:01 PR at New York.
Boston - second place (1988-1990)
New York City - winner (1989)
Beijing - winner (1987)
Fukuoka - winner (1986), second place (1983)
Tokyo - winner (1984, 1986); second place (1988)
Melbourne - winner (1983, 1984)
He also ran in three Olympic marathons (Seoul, Barcelona & Atlanta), finishing sixth in Seoul and 7th in Barcelona.
