Titanic Half Marathon organiser defends race complaints

It's two days on from the Titanic Half Marathon and some of the runners are still angry. We heard from two people on the programme yesterday who claimed the event was a shambles. No proper first aid, not enough marshalls, a shortage of water and only two portaloos for hundreds of runners. Now the organiser, William Anderson, has hit back and he is here to respond to the criticism. #BBCNolan
