FILE - In this July 18, 2014, file photo, Brazil's Fabiana Murer clears the bar during the pole vault event at the Herculis International Athletics Meeting in Monaco. One of the iconic images from the 2012 London Games was British distance runner Mo Farah capturing the 5,000 and 10,000 titles and celebrating in front of a roaring crowd. That could happen in Rio, too, with Brazilian pole vaulter Fabiana Murer. The 34-year-old Murer lives in Sao Paulo and won the event at the 2011 worlds championships. (AP Photo/Lionel Cironneau, File)
