Mo Farah's stunning 5000m victory shows he is ready for the World Championships "It was important that I won the race," he said. The conditions were tough today because of the wind, and it was a tough field, so I'm really pleased I came through it with a victory. It's important that I keep working hard now and get ready for the World Championships. On a day when many of Britain's athletes finally found top form after a quiet start to the season, sprinter James Dasaolu moved into world-class territory with a 100m lifetime best of 10.03sec in finishing second behind Jamaican Nesta Carter that puts him equal fourth on the UK all-time list. Having been in the shadow of world junior champion Adam Gemili last season, the Loughborough-based athlete believes he is now on the verge of breaking into the elite club of sub-10 sprinters. "Any sprinter in the world wants to run under the 10-second barrier, so it's definitely a goal of mine looking forward to the rest of the season," he said. Before the start of the season, Olympic 400m silver medallist Christine Ohuruogu said her mission was to prove she was not just a championship performer by winning races on the Diamond League circuit, and her ambition was fulfilled when she became the first athlete in the world this summer to defeat Botswana's in-form world champion, Amantle Montsho. In a storming finish, Ohuruogu caught Montsho in the final strides to win in 50.63sec to claim only the second Diamond League win of her career. Perri-Shakes Drayton, who won European indoor gold on the 400m flat in March, confirmed that she would be definitely sticking to her specialist 400m hurdles in Moscow after winning yesterday in 53.82sec - a season's best and the second quickest time of her career. Second-placed Eilidh Child lowered her own Scottish record by clocking 54.22sec. Olympic high jumper Robbie Grabarz also produced his best performance of the summer after several below-par outings with a leap of 2.31m that secured the "A" qualifying standard for Moscow. But there are worrying signs for Dai Greene's world title defence in the men's 400m hurdles after the Welshman finished a weary fifth in 49.55sec.
