British athlete, who, along with his great rival, Sebastian Coe (Coe, Sebastian), dominated middle-distance running in the early 1980s. The winner of gold and bronze medals at the 1980 Olympic Games in Moscow, Ovett set six world records.

Ovett first attracted international notice when he won the 800-metre race at the 1973 European junior championships in Duisburg, West Germany. He finished fifth in the 800 metres at the 1976 Olympics in Montreal. He first competed against Coe in Prague in 1978, beating him but finishing second in the 800-metre race; in that same year he set a world record of 8 min 13.51 sec in the two-mile run. His first-place victory over Coe in the 800-metre run at the 1980 Olympics in Moscow came as a surprise; equally surprising, since Ovett had been undefeated in the 1,500-metre race in three years, was his third-place finish in that event at the same Olympics.

The British press encouraged the rivalry between the gregarious Ovett, who feuded with the press, and the more reserved Coe, although in their best years the two seldom raced against each other. The one-mile world record (3 min 48.8 sec) that Ovett had set in 1980 was bested by Coe on August 19, 1981; on August 26 Ovett set another world record by running the mile in 3 min 48.4 sec, only to have Coe defeat that record (by 1.07 sec) two days later. In 1983, a week after his world record in the 1,500 metres had been broken, Ovett mustered a strong finish to set a new world record of 3 min 30.77 sec. Illness forced him to drop out of the final 1,500-metre run at the 1984 Olympics in Los Angeles.

Ovett was made a Member of the British Empire (MBE) in 1982 and an Officer of the British Empire (OBE) in 2000. His autobiography, Ovett (cowritten with John Rodda), was published in 1984.
