Tuesday was a big day for track and field at the 2012 Summer Olympics in London, featuring a pair of historic achievements. Australia's Sally Pearson set an Olympic record in the women's 100-meter hurdles, posting a time of 12.35 seconds to take the gold, while Lolo Jones from the United States missed out on a medal with a fourth-place finish.
Meanwhile, in the men's 1,500m final, Algerian runner Taoufik Makhloufi won gold, just one day after being reinstated following a disqualification for a lack of effort in an 800m heat. Leo Manzano took silver in the 1500m, becoming the first American to medal in the event in 44 years.
