Team GB poster-girl Keri-Anne Payne was the first host nation athlete to qualify for the Olympics and her long journey will come to a conclusion today in the Serpentine boating lake at Hyde Park. Payne won silver in the women's 10km swim in Beijing and will start the race in London as favourite for gold after victory in last year's world championships. In the Olympic Stadium, Usain Bolt will have to beat the in-form Yohan Blake, his Jamaican countryman, if he wants to defend his 200m crown from Beijing, while the flamboyant Phillips Idowu – injury permitting – will leap for the podium in the men's triple jump despite a season blighted by poor form and injury. There are high hopes for GB's Nicola Adams in the women's flyweight boxing at the ExCeL Centre – while in the lightweight division Ireland have their only gold medal prospect in Katie Taylor. GB's Laura Bechtolshiemer is a medal hope in the equestrian individual dressage at Greenwich Park and there's the small matter of the women's football final at Wembley Stadium.
