Olympic foils

Multiple exposures are combined to form this image of Germany's Carolin Golubytskyi competing against Italy's Elisa Di Francisca in the Women's Foil Individual Fencing round inside ExCeL on July 28 during the London 2012 Olympic Games. Francisca, the 2010 world champion, went on to nab the gold medal after beating her fellow Italian teammate, Arianna Errigo, in the final.


For the first time in Olympic history, 45 percent of the 10,800 athletes currently competing in London are women, and every nation has at least one female athlete representing them. Women outnumber male athletes 269 to 261 on the U.S. team, and Russia's team also has a female majority.

The win was especially sweet for Vos, who has been stuck in the runner-up position for the past five road race World Championships after coming in first in 2006.
