Yes---I did all that riding. I rode either before work (heading out at 4am) or after work to get in 20-26 miles/day during the weekdays. Riding after work is better because I can burn off the day's stress and I sleep like a baby! On weekends, I did longer rides, starting at sunrise. That way I could ride first and still have time for life. I averaged between 150 and 200 miles a week, usually. Sometimes more, sometimes less, depending on weather &/or how I felt physically. My longest ride was a metric century.
