My kids have now aged out of strollers and backpacks, but we had a nice jogging stroller but never really used them hiking. Only the backpacks. They are expensive and only good for a pretty limited age range, but are worthwhile if you can afford it and like to hike. I was able to get a good deal on one off of Craig's list. Just look for a decent brand. They don't tend to get a lot of use so if you can find one they are usually in pretty good shape.

Another thing to keep in mind, in wilderness areas jogging strollers are not allowed.
