Ovett went drinking with the Irish on the night he won the 800 in Moscow. I was sceptical about the story til I read an account verifying it from Mark Naylor (HJer)on the TFN MB - he says Ovett threw up in his bath.
This explains him overheating in the semi and is the real reason Coe won the 1500.
Ovett was an outrageously talented club runner. With Coe’s drive and training he’d have been unbeatable. And less loved.
