Okay Latelate Bloomer--I am 46 and was almost 220 and I ride 20-45 miles per day. I also am clipless and use mountain bike shoes as I have falled on road shoes.
I started going just 10 miles per day but as I grew to love biking more the bikes became thiner along with my butt...and the miles pile on..
My favorite thing to do is to sneak out of work and do a trail here in my area that is 40 mies.
Watch out this affliction sneaks up on you and before you know it...BAMMMMM You are a biker.
