Paula Radcliffe concerned by Vienna half-marathon time

Paula Radcliffe tells BBC Radio 5 live she is "at a loss" to explain why her performance in the Vienna half marathon was "quite so bad".

Radcliffe was beaten by Haile Gebrselassie in Sunday's head-to-head, dubbed "Emperor versus the Queen".

The Briton had targeted finishing below 70 minutes but ended with a time of 1 hour 12 min 03sec, 11 minutes 11 seconds behind the Ethiopian.
