57 and still strong,  Ruptured Achilles tendon in my late 40's.  Shoulder surgery last year, but not impairing riding.  A little slower on recovery after epic rides than years ago, but still nearly as fast....

That's inspiring mtnbikesage!  I see this was your first post.  Welcome!  Any chance you would share your back surgery type?  After two months and being almost completely recovered from my bulging lumbar disc I took some kind of nose dive this past week and am back to day 1 worse than ever. I am currently waiting to be scheduled for an MRI and they are saying I just may have to succumb to modern medicine, give up on natural recovery and go under the knife (Although it may actually be a laproscope).  I think if I had done that two months ago instead of waiting it out I would have been better off and be back to riding full speed by now!

Thanks for that info!  I got my MRI last week.  The result was an annular tear L4/L5 and a herniated disc L5/S1. I got an Epidural Steroid Injection this past Tuesday and will be rechecked on 7/21 for progress.  The shot knocked out all the pain within 24hrs leaving only some slight numbness on the outside of my left calf and foot.  Doc says no biking allowed before I have my re-check regardless of any absence of symptoms.  Been sneaking a few street only trips around the neighborhood in though!  Shhhh!
