The Duchess of Cambridge revealed her sprinting ability and punching power when she put on a sporting display with some of Britain’s best future athletic hopes. Kate burst out of the blocks as she went up against former Olympic heptathlon champion Dame Jessica Ennis-Hill and two promising para-athletes – then asked for a re-run. And she left Olympic gold medal hopeful Lutalo Muhammad joking about her “mean right hand” after the taekwondo competitor showed the duchess how to throw a punch.
