Jessica Ennis, Team GB's poster girl, performs in two of her favoured events – the 100m hurdles and high jump – as the women's heptathlon gets under way at 10.05am, giving the Olympic Stadium its first slice of competitive action. In a long and demanding day Ennis, who recently broke Denise Lewis's British record in one of the biggest heptathlon meetings of the year at Gotzis, also performs in the shot put and then, at 8.45pm, the 200m. Also on Day Seven, Rebecca Adlington is in action in the pool with the swimming 800m freestyle – one of four medal events at the Aquatics Centre (the women's 200m backstroke features 17-year-old Missy Franklin, 'the female Michael Phelps' who boasts size 13 feet). Four rowing medals will be won by 11am in a busy morning at Eton Dorney, including Katherine Grainger's attempt to improve on her three Olympic silver medals with a gold in the women's double skulls alongside Anna Watkins. In the men's coxless pairs, it's all about New Zealand's most successful export since the All Blacks (and Flight of the Concords) as triple world champions Eric Murray and Hamish Bond hope to cap a three-year winning streak with the top spot on the podium. France are virtually guaranteed a judo medal at the ExCeL Centre with 6ft 8in judoka Teddy Riner, who has lost just two fights in four years. Fans at the Velodrome can expect a ding-dong battle between rivals Britain and Australia in the men's team pursuit.
