I think it's pretty cool, it's like a form of biathlon, but not restricted to geographical location. But there's going to have to be different classes if its going to be a "sport for all". A 6'5" runner is going to have a lot of advantages over a runner who's 5'7".
Still it's got my interest, perhaps changing the knock down targets to a scoring system that subtracts from time in a point system could help even the playing field?
But I agree, it is a running sport, I even thought that before I posted.
