This might sound like a retarded question, but what is the biggest difference between running in place and actually going outside and running. I looked around the forums and didnt see much light shed on this issue. I'd love to be able to run, but there isn't much of a runner friendly neighborhood around here for me to do it in. I've attempted running early morning, only to be ambushed by bats. Mid day is nothing but traffic, hecklers, and bottles to the back, and at night the bats return. I need to train myself to run 2 miles in 14:30, which I know is attainable, but not the best enviornment to train in. Would running in place for an extended period of time help build the endurance I need for a distance run? Also, is it possible to do HITT stationary? I liked the way that looks for results, but can't imagine it working fully if I don't move 2 inches.
