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.
