I used to have a 15 mile each way commute, and I rode it on average 3 days/week. I absolutely loved it (and miss it). It took, on average, about an hour each way, and for me, it was agreat way to start the day. And to be honest, took around the same amount of time as driving (even though the driving route was about 9 miles each way) due to traffic. In the summer, I quite often met up with friends for an extended ride home. Winter is all about having the right kit.
