Rob and Romesh are on a mission to see if they can join the ranks of Team GB! Sick of being useless at sport, the duo try to find the one that even they can master. The first discipline they will be attempting is the canoe slalom, where Mallory Franklin and Kimberley Woods will send them down some sub-zero rapids. Next, they will try their hands at weightlifting before seeing if they have what it takes to be hockey goalkeepers. Hockey gold medallist and hero of the Rio Olympics Maddie Hinch will step in as their coach.
