British hurdler Perri Shakes-Drayton annihilated the competition and set a massive personal best in the 400m at the London Grand Prix on Friday.
Shakes-Drayton, 23, set a personal best of 53.78, four tenths of a second faster than her previous record, moving her into great position to earn a medal at the upcoming London Olympic Games.
Her time also ranked as one of the fastest in the world this year and put her second all-time on the British record stakes behind hurdling legend Sally Gunnell.
Importantly, Shakes-Drayton beat international contenders such as Jamaican Kaliese Spencer, Russia's Irina Davydova and reigning Olympic champion Melaine Walker.
Shakes-Drayton now moves firmly into the upper level of hurdlers for the coming competition, making her one of Britain's genuine chances at a track and field medals.
Elsewhere at the Grand Prix, Dwain Chambers, Mark Lewis-Francis and Simeon Williamson, all selected to run at the Games, failed to qualify even for the final of the men's 100 metres.
Chambers, who was a controversial selection having previously being banned from ever competing in the Olympics, looked in poor form ahead of the Olympics.
