I started riding after a 46 year hiatus a few years ago. I’m in my late 60’s and doing 100-125 miles each week. Go for it.
Fifteen miles a day, that’s pretty good!
Actually, I didn’t even have a dl until I was 40. But since then I got old, well, at least older.
So now I’m thinking I might get myself back in shape.
At what speed?
