Interesting spot I just found on the internet. I was intrigued by your 65+ thread and joined. I haven't biked in years since I was in my 30's and this week I did a 26 mile ride with three friends. I turn 72 in April so think I qualify for the thread. After I finished I couldn't figure out my thighs so called my daughter who bikes in the mountains. She mentioned lactic acid and stretching and massaging. So I did a few stretches and sat in front of the TV watching Phil Mickelson chew up the competition and massaged my thighs. What a surprise when the ache disappeared. Now I am off to tune up my FujI as I found it didn't perform like when it was new 3 years ago. This Saturday we are aiming for 30 miles.
