Late to this but I imagine my milage is 'average', btw. 2500-3000 miles/yr., probably 3.5 times cycling/wk. 50-60 miles/wk. A few lazy skip days/wks. every now and then but at least 80% of time I get the ride in. I never ride slow, mostly moderate/fast but rarely ride all out, due to my age, pushing 50 y/o. My 'fitness' is proportional to my devotion, about 10 -15 lbs. too heavy to be a badass cyclist and 'not quite' 3 watts/kilo, more like 2.25. Resting HR 52-56 bpm in mornings. (40-60 is the range for 'Athletes'). At 6'4" 215 lbs, I'd say I'm just your 'avg. fit recreational cyclist'. Not too bad, nowhere near great. I can't keep up with the fastest group riders. Few can.
