Well, tomorrow is officially three months out from surgery, so I thought I would post an update. It will probably be in somewhat random order.
I have caught myself at work walking fast down the hallway like I used to, without thinking about my hip. Someone posted something about walking like you are gliding and that has really helped me on not limping out of habit or tiredness. (so thank you whoever that was!)
I am going to spin class, but still taking it a little easier than I used to. Part of that is out of necessity as I am out of cardio shape, but it is improving! I also do the elliptical, as it seems to irritate the hip less. It is most effective for me to ice right after class, for controlling irritation. I will start formal PT this Friday, as my OS prefers just walking and light (stationary) biking until then. I noticed at 12 weeks, that my hip seems to be just generally getting less irritated, which is great! Also, my energy level is quite good. I still have to watch that I get enough rest, and I don't do much after work (I work out at lunch), but I haven't "hit the wall" in a long time ::knock wood::
This past weekend I started on my hiking training. A friend and I did some "urban hiking" with the dog. First the offleash area trails, and then we found another park that has lots of elevation gain variations, so I can train for steeper hikes. We probably walked around 3 miles. I had a light pack on this weekend, but when I "train" I will have my regular hiking day pack with the usual stuff. The "training" won't start for a couple weeks, at least. I don't want to start adding too many things at once.
I still have tight spots, on my front thigh and glutes. One of the best things was a recommendation from @Cardie to do the leg roller - works great on the thigh, ok on the glute, and IT band is starting to loosen up. The glute issue has been around for awhile (long before surgery), so I may have to work with a massage therapist on that one.
I have started back to Weight Watchers, and have dropped 3.5 of the 14

pounds that I gained during my "convalescence". I did pretty well at first, but then there were the holidays and a few too many trips to the famous bakery!
At work I am starting on a big project, so I will be busy there too. As others have said, the pace of progress slows down now, but I can still say I have improved a lot from a month ago.
