This is an interesting little video of the GPS plot for the final leg of the Women’s relay at the 2012 WOC. It needs a little explanation. The Finish team make a terrible mistake at the second control, visiting control 6 on the way, but fight back throughout the whole leg, to win by a matter of metres at the end.
What surprised me was the way the relay was gaffled, with mostly common controls and only three different blocks of three controls.
Moral: Never give up in a relay!
