I will be 66 in September.
I ride a 2001 Litespeed Tuscany TI
I take Vitamin D, Glucosamine/Condroiton
I rode bikes as a kid, but never serious riding until August 2010. I weighed 240 lbs when I started. I weigh 190 right now and in better condition than I have been in years. I would really like to drop another 10 lbs, but that is getting really tough now. I am not a strong as I once was, but I think riding is helping prevent any further loss of strength.
I always ride solo and ride 3-4 days each week, usually 25 miles but have gone 50 miles on many occasions. I average about 15-17 mph on rides up to 50 miles. Never tried to go farther than that. Limiting factor is my butt. I can't seem to find a saddle that is completely comfortable.
Because I live in the Dallas area, I can usually ride year round, so I manage about 4-5000 miles per year.
I should have taken up riding a long time ago. Don't know why I didn't!
