Rob and Romesh are on a mission to see if they can join the ranks 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.

In this very special edition, Rob and Romesh will be hanging out with British sporting legend, Sir Andy Murray. They'll catch up with him as he models his new sports wear range, before being pushed to their limits in a tennis training session and Andy's favourite hobby, road cycling. Their mission is to try to get to know what makes the greatest British tennis player of all time really tick.
