There was an attempt at a GB leadout, but it didn't work.
Just before the last corner, the Australians had the front of the peloton, and Stannard, G and Cav were moving up to the front between the Aussies and the barriers, One of the Aussies saw Stannard come past and moved over immediately behind G to block Cav.
Having been blocked, Cav just got on Goss' wheel. Stannard and G got round the corner, realised that Cav wasn't there to lead out, and hesitated to look for him.
