Hurdler Perri Shakes-Drayton outraced some of her main Olympic rivals when she clinched victory in the 400 metres hurdles at Crystal Palace, setting a personal best in the process. Shakes-Drayton's time of 53.77 seconds is the second fastest time ever run by a British woman. It is also the joint second fastest time in the world this year. No wonder that Shakes-Drayton was overjoyed after her performance.
There was no surprise in the men's 5,000 metres where Mo Farah provided a devastating last couple of laps to break the field and surge to victory. The world champion won in 13 minutes, 6.04 seconds in his last warm-up race before the Olympics.
However, there was disappointment for Dwain Chambers who ran a time of just 10.35 seconds in his 100 metres semi-final. He finished fifth which was not enough to qualify for the final. Afterwards, he described the run as "terrible".
