Sonia O'Sullivan and Paula Radcliffe, who are both targeting major North American marathon titles in the next few weeks, clash head-to-head in London's Richmond Park on Sunday morning in the Nike London 10km Fun Run.
O'Sullivan is totally concentrating at the moment on the Great North Run and is using Sunday purely as a fun run. Immediately afterwards she will fly to New York where organisers there will announce this year's worst kept athletics secret - her participation in the Big Apple marathon on November the 3rd.
