Virginiacyclist, You are definitely on a much more aggressive PT program than I was. Was that prescribed by your OS and are you currently working with a PT? I was allowed to return to cycling before given the OK to begin running (jogging). I was allowed to begin a walk/jog program once I was able to walk pain free and without symptoms for 45 minutes with hills. I used a treadmill and switched back and forth between flat and the highest incline setting on the treadmill (15 on mine) so that half of the 45 minutes were walking up hill. I began the walk/jog program at about week 15. The program I was given by my PT can be found on pg 92, post #2747 of this forum. Once I completed the walk/jog program, I was given an advanced running program that can be found on page 95, post #2849. I don't know about the PT or trainer to seek. I know my PT personally and know him to be a runner and cyclist. He also worked closely with my OS who work down the hall from each other. During the running programs he really wanted me to get off the treadmill and run on a track or a surface similar. I'd just caution not to begin jogging too soon and like your OS said, be respectful of the suregery. There is a lot more stress on the repair site while jogging than cycling. Another thing I did/do, but wasn't specifically prescribed by the PT, is to walk stairs. I walk up and down stairs. Once I did that easily, I walked up the stairs two at a time (but not descending) Sounds like you are doing pretty well though. Do you have full ROM?
Best of luck...Ken
