Three-time London marathon winner, women’s marathon world-record holder and the BBC’s 2002 Sports Personality of the Year, Paula Radcliffe, 38, is an internationally renowned long-distance runner. She is perhaps best known to Londoners for rather publicly answering the call of nature at the side of the road during a 2005 marathon. Brits are speculating about whether Radcliffe, a mother of two, will live up to her talent at the 2012 Summer Olympics, after she finished with her slowest time to date at a recent half-marathon in Vienna following an unfortunate bout of bronchitis.
