Im reading Bill Rogers autobiography, and it has made me realize that Bill was a BEAST. He ran 2:09.27 in Boston, which puts him right up there with Scott Fauble and Jared Ward, but 40 years ago. Since then training, nutrition and equipment are obviously much improved. If Bill rodgers had a pair of alpha flys and you put him on that berlin course on a perfect day, what would he run? I think he could break 2:07.
Dick Beardsly and ALberto Salazar both ran 2:08 at boston. Greg Meyer ran 209 flat. Get these guys some vaporflys, perfect pacing, that special maurten drink mix, and I think you would see some special times.
Even as recently as Ryan Hall, he ran 206 in london. If he had the magic shoes I bet he could run close to 204 high.
