Chinese runners compete in the women's 4x100 relay at the Rio Olympics in Rio de Janeiro, Brazil, Aug. 18, 2016. In one of the strangest sights ever seen on an Olympic race track, the U.S. women's 4x100 relay team were given a second shot at qualifying in Rio after dropping their baton in their earlier qualifying heat on Thursday. They finished the re-run in a time of 41.77sec to beat the time set by eighth-place qualifier China (42.70sec) and advanced to the final. (Photo/Agencies)
