I find it near impossible to believe a guy who is running a 4:14 mile, and has struggled consistently for years now in what should have been his prime years, was ever doping when he ran 3:31 for the 1500 at a young age, so that leads me to the honest question, is that 3:30ish neighborhood the limit for non East African men?
Alan Webb, 3:30.4 pre super shoes, Buster Mottram was 3:32 pre super shoes, Gregson was 3:31 pre super shoes...thoughts? So maybe with new upgraded shoes, 3:29.xx?
