2010 London Grand Prix

The 2010 London Grand Prix was the 58th edition of the annual outdoor track and field meeting in London, England. Held from 13–14 August at the Crystal Palace National Sports Centre, it was the twelfth leg of the inaugural IAAF Diamond League – the highest level international track and field circuit. 40 events were contested with 27 of them being point-scoring Diamond League events.

Rain fell both days and temperatures were described as "cold" by the BBC. Despite this, 2008 Paralympics champion Oscar Pistorius for South Africa, running in the men's T44 (below knee amputee) 400 metres event, set a new world record with a time of 47.04 seconds. Though the time was slower than his personal best set in Italy in July of the same year, 46.02 seconds, his personal best had not been run in an International Paralympic Committee sanctioned race, making his 47.04 seconds race on 14 August the official world record.

Meet organisers hoped to stage a competition between the three fastest men in the world&mdash;Usain Bolt, Tyson Gay, and Asafa Powell&mdash;in the men's 100 metres. However, Bolt declined to participate, claiming he would lose more money than he would make because of British taxes, and Powell withdrew the day before the race with injuries to his hamstring and back. With Bolt and Powell absent, Gay won in a world leading time of 9.78 seconds ahead of Yohan Blake, who finished second behind Gay in a personal best time of 9.89 seconds. Gay's time was also a stadium and meeting record, and his victory made him the top ranked 100 metres sprinter for the season.

Other notable records in the men's events included a meeting record by Gerd Kanter in the discus throw with a mark of 67.82 metres, and an equalling of the 110 metres hurdles meeting record of 13.06 seconds by David Oliver, originally set by Colin Jackson in 1992.

In the women's events, Priscilla Lopes-Schliep won in a world leading time and meeting record of 12.52 seconds in the 100 metres hurdles, making up a metre deficit from the 50 metres mark to pass Sally Pearson who finished second in a time of 12.61 seconds. Milcah Chemos narrowly held off Yuliya Zarudneva in the 3000 metres steeplechase, winning in 9:22.49 to Zarudneva's 9:22.60, both under the previous meeting record. Allyson Felix doubled in the 200 metres and 400 metres sprints, winning the former by half of a second (22.37 seconds to Debbie Ferguson-McKenzie's 22.88 seconds), and narrowly winning the latter in 50.79 seconds ahead of Tatyana Firova who placed second in 50.84 seconds.

Diamond League results
Top three placers in each scoring event earned four points, two points, and one point for first place, second place, and third place respectively. The athlete with the most points in a Diamond League event (e.g. women's 100 metres) at the end of the season wins the Diamond Trophy for their event.
