Why couldn't coe have broken or been close to every world record from 800m-10000m in his day?Is it impossible to excel at every distance from 800m to 10000m? If so how do you account for Said Aouita?
At the same time as running world class 800 and 1500m times? In training? at night? in sheffield?
I think that we should be asking why we SHOULD believe it rather than why we shouldn't!
