James and old friend Gordon Ramsay, an Ironman finisher, hop on a pair of treadmills programmed so each controls the other's equipment. Once the treadmills are up-and-running, Piper Perabo poses questions to each of them -- James's questions about cooking and Gordon's about boy bands. Get one right and the incline goes up for the other person; get one wrong and your own speed goes up. | The Late Late Show with James Corden
