Two-time Olympic medalist Kelly Clark has been winning halfpipe contests since she first started entering them in the late '90s, but like most competitors she has had her on and off moments over the years. Then 2011 hit and Clark proceeded to win 13 contests in a row. She went on to finish out 2012 with a total of 19 first-place finishes to her credit.
