commute 40 miles/day round trip - usually hit up a fast group ride or training race or two during the week. I like to go for a long ride on Saturdays. Sunday I usually take off. Last week I hit 310 miles. This week I'll have 180 by the end of the day.
My results are kinda skewed because I can't afford/refuse to pay to use gas all the time for my SUV. I'm perfectly capable of covering the distance by bike so there's really not any reason other than laziness to not do it.
Before my commuting days I'd probably average about 150 miles/week.
