I don't really care either. I am having fun on each ride!
I have been able to challenge myself and do more over time. It's just funny to me how many people were talking about riding 30, 40, or 50 miles and more, and still talking about being slow.
As much as anything, I guess I'm poking fun at myself. As long as I still have to use my "granny gear" I don't think i'll worry about running out of gears on the top end.
Oh, i'm not worried about wind drag on my bike. Even the widest part of my HKEK is still just a fraction of the width of the girth that is me.
