Going 13.1 miles on the treadmill for half marathon training is very hard. Why? Because it is so easy to just turn it off and quite. Walking/running outside you can turn around and head home, but sometimes that is longer than finishing, or at least fairly long. But it can be done on the treadmill.
I tended to rent a season of a TV show I had seen before, but a very rewatchable series. IE I don't want a new show that I will get too engrossed in, but something I have seen, but love rewatching. And the fact that it is renting a whole season from the library, means you have to watch it in one week, or recheck it out. Means you have a lot to watch. Now I prefer the videos I don't have to keep telling it to play the next video. Sometimes that is hard to do with how the treadmill and tv/vcr/dvd player line up. I have also done music with my ipod shuffle, but for some reason, that doesn't do it as long for me. Or, sometimes I rented long movies that would keep me interested. Hard to find a movie quite that long though, hence the seasons of tv.
Good luck to you, but try and do some outside when you can, as treadmill is so different than outside, and yes, I think doing a half marathon for me wasn't about the physical distance, more about the mind game. Oh, the thoughts I had in my head walking my first and only half marathon. Walked outside last week for a 12 mile walk and oh, the thoughts were similar, but not quite as bad. Calling myself all forms of a crazy woman. I mean, who walks a half marathon? And why?
