Staff Sgt. Alex Mace runs 1.5 miles during his physical fitness test June 27 at Aviano Air Base, Italy. One year ago, Mace took a jump too fast on a mountain biking trail in Piancavallo, Itally and the resulting crash snapped his sternum, lacerated the upper quarter of his heart, dissected his aorta, caused him traumatic brain and spinal cord injuries that left him paralyzed, broke both elbows, his wrist and all the ribs on his left side, which in turn pierced both of his lungs, ruptured his liver and his kidneys. In June, Mace scored a 92 percent on his physical fitness test. (U.S. Air Force photo/Staff Sgt. Ryan Whitney)
