From oldest to newest the miles I put on each bike were:
Univega - 943, my old favorite gets almost $1000 miles.
Bridgestone - 1611, "The Tank" gets a lot of winter, bad weather miles.
GT 1.0 - 904, Over 900 miles on an off-road bike is a lot!
Scott - 287, Hmm, my lightest, fastest bike seems a little neglected here.
Surly - 2038.6, But the bike I got at the beginning of the year seems to have taken up the slack.
GT 9er - 70, Only 70 miles? OK, I've only had it a week.
2012 was a year for other firsts too. My first 5K (and second, and third, and fourth). My first mini-triathlon, my first off-road triathlon (8th place) and my first cyclocross race (nowhere near 8th place).
I think 2013 will be a year of fewer firsts but I'm going to try to improve the foundations I built in 2012.
Happy New Year
