Johnny Vegas, Richard Whitehead, Jody Cundy & Jon-Allan Butterworth

Adam Hills, Josh Widdicombe and Alex Brooker are joined by special guest Johnny Vegas for an irreverent review as Day 4 hots up. There's a very special performance from Superhuman and 2012 hero Richard Whitehead, who looks to defend his 200m title later, and stars of the Paralympic velodrome, Jody Cundy and Jon-Allan Butterworth also join the boys in the studio. Expect sketches, tomfoolery, clips, chaos and the always entertaining and often illuminating, bordering-on-the-unacceptable #isitok questions from viewers and athletes alike. Packed day: packed show.
