A Russian skier,Anton Gafarov, was trying valiantly to finish the race after a bad fall. He had broken one of his skis but was trying to will it to the finish line. After falling again, a Canadian coach hurried onto the track and gave him his ski to allow Gafarov to finish the race with some dignity.
You can catch it between about 30 to 60 seconds into the video on this page.
Call it payback of sorts because in 2006 a Norwegian coach threw her ski pole to a Canadian skier, Sara Renner, who had lost hers. Sara went on to defeats Norway's own skier, but the Norwegian coach, Bjornar Hakensmoen, thought it was the fair thing to do.
By the by, the Canadian coach is Justin Wadsworth, who was born in the USA. So, I guess four countries were involved in this affair: Canada, Russia, Norway and USA. Pretty neat, eh?
