I guess most of us on NS are too downhill oriented. Here's a little info on Biathlon:
Originated from the use of ski soldiers. Finland is especially good at biathlon thanks to their background in skiing. Finland held off the entire Russian army in the winter for months before finally being forced to surrendur.
In the summer, there are biathlon competitions. They generally use paved trails and rollerskis, however there are running biathlons as well.
