Many people say they don't like running, either because they find it uncomfortable or w/e. The thing is, running isn't going to be comfortable. Now if you have a history of being inactive, it's going to be painful at first, but like all things, it gets easier with time. It takes about a month of running on a regular basis for one to be able to be able to think, "Oh, it's nice out, I think I'll go for a run." If you want to become a better runner though, it's going to take a bit of pain. However, I think running is more enjoyable with the hard workouts because that makes the easy runs all that much more enjoyable, and it makes it less repetitive (doing the same workout every day) It's kinda like the easy runs are "rewards" =)
Sorry for the wall of text.
