From Brit point of view Jessica Ennis 800m race at WC. To set off so exuberantly fast (27.xx 200m) when there was no need whatsoever, then hang on for the win

Overall, Bekele at WC's. He did look beat slightly for speed to me too. The wiley old fox Lagat did every more at the right time, a text book performance, but still somehow Bekele found something extra.
Saw Ritz online too. That's what running is all about to me. So many races are just a procession with everyone filing at a set pace around but he was running like a man possessed on those last few laps
