Thanks Eldoret, Seb and Peter Coe really worked amazingly well together.
What I think was the biggest factor in Coe's talent, was his confidence. You can see it when he is being interviewed, both now and back then. Considering how young he was, and how he was the most famous runner in the World, he was remarkably relaxed in interviews, as though the pressure of being World number one was actually enjoyable.
I think this confidence also shows in the training, the ability to peak at the right time, he was rather good at that.
