Career Highlights: After competing in the 5,000 meters and failing to medal in the last two Olympics, Shobukhova’s best chance of reaching the podium appears to be in the marathon in London. She made the transition from middle-distance running to the marathon after finishing 19th in the 10,000 meters at the 2009 world championships. She has had no trouble with the 26.2-mile event, finishing first among females in the Chicago Marathon in each of the last three years, while also winning the 2010 London Marathon. Shobukhova’s years of competing in middle-distance events has been instrumental to her success in the marathon, as her final kick down the stretch reaches a speed similar to her finishing strides from the shorter events. With a time of 2:18.20 at the 2011 Chicago Marathon, Shobukhova recorded the second-fastest women’s marathon time ever. Her biggest adversary in London is Great Britain’s Paula Radcliffe, who owns the women’s world record with a time of 2:15.25.
