If you've ever completed a marathon or half-marathon, you've probably felt that sudden dread when your legs just stop working.
Unfortunately for many, this tends to happen when the finish line isn't far away. One woman had almost made it at the Philadelphia Love Run Half-Marathon when her legs started giving out. She was trying her hardest to walk the last stretch, but it was clear that she was hurting too much to go any farther. That's when two kind runners decided to give up shorter finish times to help her cross that line.
