London 2012 Olympics: Jessica Ennis takes heptathlon lead in Gotzis after no nasty hurdle surprises On her last competitive appearance at the CityGames in Manchester, Ennis seemingly ran a personal best of 12.75 seconds in the 100m hurdles, only to later discover that just nine hurdles instead of the required 10 had been set out on the track. This time all 10 hurdles were present and correct - her coach Toni Minichiello making a point of counting them personally - and Ennis cleared them all in 12.81secs to win the final heat. That was just 0.02secs outside her personal best, making it her joint second quickest ever run and also a stadium record, while also being worth a 32-point lead over Canada's Jessica Zelinka. Russia's Tatyana Chernova was 79 points behind in fourth and Olympic champion Nataliya Dobrynska 170 points adrift after finishing last in her heat, although Dobrynska revealed yesterday her training had been understandably disrupted by the death of her husband and coach Dima Polyakov two months ago.
