I think it's funny to pose this question exclusively sub4 guys and not any sub/elite college guy.
It's pretty boring at times, or at least it would appear that way to most people. I find it ironic that to be the best exerciser you have to be pretty comfortable with living the sedentary lifestyle as well.
There is a lot of downtime, and early nights but if you get really into the process it is probably a lot more satisfying than many college kid's experiences. If you have a good set of teammates to do it with and keep things fun, then sitting around and playing video games and watching movies can be a good night in.
I find that a lot of elite runners have girlfriends because it fills up a good chunk of time, and is a way to "get some" without sacrificing sleep and lifestyle. Being single is especially lonely for a dedicated distance runner.
Also, it's definitely a true statement that when most college runners rage, they rage real hard. I am dull though. I mostly just eat lots of ice cream which makes me sad and feel badly about myself.
