I guess you could call it conservative in the "6 months to run" camp. In the "one year to run" camp, it is aggressive. Just depends upon your surgeon's protocol.
After starting to "run" at 7 months and now being right at 13 months, I understand a bit better both sides of the coin.
I went EXTREMELY easy for the beginning. First, you have to understand that up to that point, I had gotten my long walk up to 6 miles at a very brisk pace every couple of days and was also swimming 2500 meters a couple of days a week and cycling up to 50 miles per ride a couple of days a week. That is all fine and good for general health, but, for me, did NOTHING to prepare the soft tissue for the stresses of running.
At 7 months, I ventured out to try to start running. I would warm up with a walk of a mile to mile and a half and then jog for only 50 yards or so. Then back to walking for a few minutes. Then another short jog, and so on for a total of around 5 miles.. In the beginning this was long walking and just some occasional light jogs for a VERY short distance.
Over the months, I would bring the running distance up a little every couple of weeks. At a couple of months into the running, I started doing 1 minute run, 1 minute walk (after a long warm up walk) for a couple of miles. That would push it. Every time, it would get sore, but some days it would be just the soft tissue complaining and some days it was pretty bad and refused to cooperate. I iced my entire bum, and upper thigh by wrapping big ice packs all around it EVERY TIME. ICING IS CRITICAL FOR RECOVERY!
Since I needed to stretch out the distance for the upcoming event and there was no way I was going to run the whole thing (I couldn't run over a quarter mile at a time without walking), I simply walked a lot more and ran a little more in the sessions.
I had days where I could hold an easy run during the sessions for up to 3 miles, but these sessions were irregular and unpredictable. There were good days and there were bad days. By 11 1/2 months out from surgery, I got the whole thing up to a long distance of 13 miles once a week and 6 mile short sessions in between. The 13 at that point was WAY TOO MUCH. Although I did have some good sessions right before the race where I ran a lot of 1, 2, and 3, mile segments in the long session, there were some really bad ones in there too. I could feel that I was just pushing too much too soon and resigned myself to doing mostly walking in the event run portion and allowing another year of working on it before I could go out and really push.
In retrospect, I would definitely do the first 7 months of my rehab exactly the same way. The difference would be that when I started running again, I would have stretched out the very short jog period for at least another 3 months. I would have then doubled the time to gradually slide up the distance and run segment intervals. To simplify, what I did in 5 months (7 through 12) I would stretch out to 12 months (7 through 19).
The one other thing is that I have read from other hippies that the illopsoas and psoas can be very painful after this surgery when pushed to come back and will cause exactly the deep tissue soreness that I keep getting. A deep tissue expert / specialist in resolving this is reported to help tremendously. I blew off PT because I could tell they weren't specifically knowledgeable about this operation and were appying a template treatment that was going to actually do damage (like those leg lifts early on which are a big NO NO).
Hope that gives some helpful info, but remember the standard disclaimer: Everyone is different so PLEASE listen to your body and don't take others experiences as the way it should go for you. The body is usually pretty good at telling us what we need to do. We just suck at listening much of the time. I have the listening part down pretty well, now I just need to learn to stop arguing with it so much.
