This program covers four incredible team efforts: the coordination of muscles, bones, heart and circulatory system that makes Mike Powell the world's greatest long jumper; the struggle of one climber to survive the onslaught of infection; the digestive dynamo that turns a simple sandwich eaten by five-time Olympic gold medalist Bonnie Blair into raw energy for a blistering sprint down the ice; and the ultimate event - the development of a new human life inside track star Karen Hatchett.
