Until I retired, I commuted to work, 60 km round trip 5 days per week. I also sometimes did a couple of evening rides during the week and a couple of much longer rides every weekend. At times I rode up to 100 days in a row averaging over 500 km per week. My 30 km commuting ride usually took me an average of one hour, depending on wind direction. My 30 km ride home was usually faster than the morning ride to work, because I preferred to arrive without sweating too much since we didn't have showers at work. At the beginning of the season, I would find the ride a bit tiring, but by mid season I would often extend my ride home because I found it bit short
