Well today I was really shocked. I was riding to school which is about 17 miles away and I had just gotten to about the 10 mile mark when this guy on a full zoot cervelo caught up with me. Stops next to me at a light and said, damm for a big guy you sure can move fast. He proceeded to give me a few tips and then check out my Salsa. I really liked his bike as well I was definitely riding and smiling after I dropped him (dunno how really) I don't really feel fast. I tend to ride about 18 to 20 mph on my commute and he was doing about 15. Mind you this guy was about half my weight. Pretty shocked right now why in full kit with at least 5 to 6k below him he was moving at this speed. I will keep up my 350 to 400 miles per week.
