I started commuting to work and putting LOTS of miles on my road bike in May 2013, and finished 2013 with 2,500 total miles for the year. I just wanted to do at least 3K for 2014 and ended up doing over 3,600 miles. Had hoped 2,500 of that would be commuting but came in just short. Would have made it if I hadn't overslept yesterday.
