FILE - In this Friday, Aug. 5, 2011 file photo Brazil's Fabiana Murer competes in the women's pole vault during the Diamond League at Crystal Palace stadium in London. The world pole vault champion lost a chance to compete for a medal in the Beijing 2008 Olympics because one of her poles was misplaced in the final, so the Brazilian is promising to keep a close eye on her equipment to make sure nothing will get in the way this time.
