DUDE-- You are doing great !!!

I've been riding about a year, 5'10"240# and ride a Giant OCR Limited -- Carbon frame, Ultegra components, 700x23 hi pressure tires, aero bars, etc, etc. It is a far better bike than this rider deserves. I average about 15-16 mph on a 20 to 40 mile loop -- well below most of the riders in my group.
And you ride a hybrid???

Measure yourself against only yourself. Keep riding & you WILL get stronger & faster.

Ride Fast, Ride Safe & Have Fun
