At the 1992 Barcelona Olympics, British runner Derek Redmond was finally healthy and running well in the 400-meter semifinal. About 150 meters in, his right hamstring tore and he crumpled to the track. He waved off the stretcher and started hobbling toward the finish. His dad, Jim, pushed past the officials, came onto the track, put his arm around his son, and helped him along while 65,000 people stood and cheered. Right before the line, Jim let go so Derek could finish the race on his own.
