I dunno how many biathlons they run in Europe a year, but it can't compete with the number of baseball games we have.
I find nothing fascinating about watching cross-country skiing, although adding the marksmanship aspect to it is an interesting twist.
It would be like adding archery stations to the Boston Marathon, I guess. Kinda weird, but exciting?
