He ran 20.7 or .8 this year, previous best was 21.3 when he ran 45. In 2007. I think he was carrying an injury after that early may 200m run this year,which may explain poor 400m times, as he did get faster with each race later in the season. Injuries have been present in pervious seasons as well, but a major overhaul of any training program that got u to elite level is never a good idea. If anything, he prob needed to stick with his old program and do less volume than ever before,more recovery, more therapy, more intensification in the special end runs in the final spp.
