I never smoked (well, smoked dope for a few years, "I went to college!") but my average speed is a couple mph below the magic 15mph you ex-smokers seem to get!
I'm stuck in the 13 - 14 mph range and some rides down in the 12's!
I still have a fun time riding though, so no complaints! Here's a link to my last big ride (last Saturday) . . . stuck (slowly) at 13.2!

I want to be 15+ mph fast like you guys!
