Nordic Combined:
Now imagine that it’s the dead of Russian winter (you know the environment that has defeated more enemies than the French), and you are miles away from the base of your camp. You don’t know how to get to your destination, but you also know that there is a giant gap impeding your progress. This means you have to ski all the way there and perform an impossible jump, which is pretty much the situation that describes Nordic Combined. In this sport you cross ski 18km and perform a ski jump. It seems pretty extreme, but these athletes have been training their whole lives, so they got it.
