At 66 , I ride at least a couple of times a week. I don't go too far but on my Sunday rides I do 30-40 miles and that keeps the body and mind happy. I have ridden since I was a kid without ever stopping. I have ridden more or less at different periods of my life , but always done some. I have not had a weight issue so I don't deal with that but I have hypothyroidism which messes with my energy level at times. Your body is your best gage and will tell you what you are capable of . Also weather, I am in Southern California so I cycle year round and I don't much car for trainers but I would do it if I were in the Northeast right now! Joe
