Stephen Mangan, David Weir, Libby Clegg & Chris Clarke

Stephen Mangan runs interference for Adam Hills, Josh Widdicombe and Alex Brooker for an alternative look at the day's events. David 'Weirwolf' Weir gives a very special performance ahead of his 800m heat this evening, and Paralympic sprinter Libby Clegg and guide Chris Clarke drop in. Expect more sketches, clips, and whip-like wit and nothings-off-limits #isitok questions from viewers and athletes alike.
