Here's the stadium with (L to R) the shooting range, the start area, and the finish line. We saw women's 15k individual and men's 20k individual biathlon. The competitors start 30 seconds apart, and get a 1-minute penalty for any missed shots. There are 2 prone and 2 standing shootings, 5 shots each. The targets for prone are very small, and the targets for standing are a little bigger. In other biathlon events there is a penalty loop for missed shots. The skiing is freestyle, which means they are skating.
Check out the selection of skis. We were surprised by how much warming up the athletes were doing considering they were about to ski themselves silly. Guess they need to test out the waxes and the course conditions. It was maybe 5 degrees C so the snow was a little mushy. If you've ever tried skate skiing then you know how crazy it seems that these guys (and girls) compete in multiple biathlons with only a day or two of rest in between, and that they are able to hit these tiny targets with heart rates around 180 bpm.
Skiing with a gun: awesome.
