Incroyable! French relay runner's astounding final leg snatches gold at the line

France won the women's 4x400m relay final in Zurich yesterday with a final leg that has to be seen to be believed.
When the final runners took their batons the competitors from Russia, Ukraine and Britain were in a tight trio metres ahead of French runner Floria Guei. It looked as if the only question to be decided was in which order those three would win medals.
