Triumphant Allyson Felix feels the love at her 'second home" the Olympic Stadium Renaud Lavillenie, France's pole vault champion, delivered perhaps the finest display of the day, producing the best vault of the year, 6.02m, and then having three fairly unthreatening cracks at increasing Sergey Bubka's world record to 6.16m. With Australia's Sally Pearson winning the 100m hurdles, the Oceanian flag was also flown by New Zealander Valerie Adams, who won the shot with a world-leading 20.90m winner. Adams, cruelly robbed of receiving her gold medal in the stadium last year which went instead to doping cheat Nadzeya Ostapchuk, deserved her thunderous ovation. One shocked Olympic champion was Jamaica's Shelly-Ann Fraser-Pryce, quite brilliant in the 100m heats, but beaten into fourth place after a terrible start in the final as rising Nigerian star Blessing Okagbare set a new African record, 10.79sec, to triumph. A marvellous 61st edition of one of Britain's most famous races, the Emsley Carr Mile, was won by Kenya's Commonwealth champion Augustine Choge, who ran a last lap of considerable courage and strength to hold off a late surge from Djibouti's Ayanleh Souleiman and prevail by 0.06 seconds in a lifetime best 3min 50.01sec. Choge, watched by one of the illustrious list of former winners, Lord Coe, was thus able to sign his name for a second time, following his other win in 2010, in the pages of the race trophy, the famous red Moroccan leather-bound book. The Olympic 400m hurdles champion, Dominican Felix Sanchez, who 12 months ago shed tears on the podium after regaining his title at the age of 34, cut a frustrated figure as he trailed home last in a race won by American Michael Tinsley.
