Painless is how I would describe my commute today - first time in years! I finally decided to get a cortisone shot in my left knee last week, after dealing with off/on pain for the past 2 years. What a difference! I'm trying to get my mileage up so I can do a century next month. It appears now that I'll be able to do the century. It might take me a while but at least I can train without pain. What a relief.
