In February 1988, the American speedskater, Dan Jansen was told on the day of his Winter Olympic final that his sister had died of cancer. Stricken by grief, he then fell during his race. It took Dan Jansen another six years - and five more races - before he finally won gold and completed one of the most emotional laps-of-honour in Olympic history. He spoke to Simon Watts in 2014.
