Watching two hours of Biathlon tonight! One hour each of men's and women's.
I have always known that I am not a runner, and never have been. But, for a while I simulated biathlon to improve both fitness and shooting. We had a NordicTrak for many years, and I had a perfect ten meter range in our family room. I struggled to do half an hour on that machine at an average pace, even when watching action movies. But, play the biathlon game, and I could put twice the time and triple the distance on that thing.
I read an article on biathlon several years ago. The coaches said that it takes many physical factors that can't be developed through training. These factors can only be honed. However, they can teach almost anyone to shoot. So, they take world class runners, put them on skis, and teach them to shoot.
