For the past decade - after one knee was "scoped" - my tactic has been to delay as long as possible, the inevitable knee replacement my doctor envisioned. I have dealt with the pain, through grimaces, ibuprofen, CBD, and some cross training. I spent the last two months guiding treks in Peru and Chamonix, and am now training for a 50 mile race.
However, I am still wrestling with the question: When is the right time? I pulled up this important opinion which I had remembered from The Uphill Athlete website.
