As another over 50, post menopausal, hadn't been on my bike in, uh, years type, I started out a year ago huffing and puffing at a very slow pace around a 9.7 mile loop here in town. 35 lbs later, my sister and I just finished a 72 mile ride around Lake Tahoe. Yes, you can get back on your bike and have more fun than you can imagine. I've met so many great women, in their 50's and 60's, out riding. Go, girl.
