The beauty of sport is its ability to surprise and Isaac Nader produced one of the biggest ever in international 1,500 metres finals as he won the world title on Wednesday while Katie Moon was a more predictable winner of a third successive pole vault crown.
Portugal had never had a medallist in the 1,500m but Nader's storming run in the home straight was enough for the 24-year-old to deny Jake Wightman of Britain a second title.
