I was 43 when I had the AVR in 1991. Of course I did very little running the years prior and following OHS, but I was a runner for decades. So, I compared running times that I had 2 years before and 2 years after the surgery. Before the surgery I could run a mile in about 6 minutes and a 5K under 21. Then afterward the times were an 8 minute mile and 25 for 5K. In retrospect, I believe I could have trained harder than I did and come fairly close to the times I ran earlier. One problem with that is I was in virgin territory. There was no forum like this to help me and no one I ever met who had returned to athletics after OHS. In all, in 40+ years, I ran over 500 races from 200 meters to half-marathons, 150 before the AVR and yes, 350 events after.
