Ben Shires, Al Jackson and Haruka Kuroda witness record attempts from around the world in front of a live audience. The challengers include the world-famous Moscow State Circus attempting a fiendishly difficult juggling-leapfrogging record, and an incredible jet-powered surfer. Our Officially Competitive heroes compete in an unusually tricky walking record, and someone comes face to face with a tank full of gunge.

This episode is an Olympic special, featuring record attempts by Olympic gymnast Nile Wilson and gold medal-winning Paralympic archer John Walker. Also there is a precarious glass-stacking record. And one of our Officially Competitive legends will be hoping to be saved from the gunge tank of doom.
