MMR says 2351.6 miles. I'm terrible at using it properly, tend to forget it entirely, pause it then forget to resume when I move again, or let the phone battery die and lose the data entirely. So, I'm going to go with 3,000 miles as my official total for 2013.
I had declared a goal of 5,000 miles for the season, back in March. I knew at the time that was unrealistic, simply due to time constraints alone. So, I'm pretty happy with 3,000.
My 2014 goal should be 5,000 and do it -- I should pick up speed hence miles on the road bike.
