For the record
Commuter bike starting odo: 5818, ending: 7815, total: 1997 commuter miles
Road bike starting odo: 8457, ending: 13791, total: 5334 roadie miles
Fixed gear bike 247 (normal ODO) 234 (garmin) 100 (est unrecorded commuting miles) 581 miles
I sometimes ride the commuter as a mountain bike, or on errands, so those miles are not strictly "going to work" miles.
I ride the fixed gear/single speed for fun, and commuting. The light I use interfeared with wireless odometer, so I guessed 100 miles unrecorded. I'm sure there were really more.
I'm a bit disappointed. Had I known I was so close to 8000 I could have made it by just adding a few a day, or taking one good ride. Of course, I find I'm also thinking "Perhaps I really did 180 unrecorded miles on the single speed." But that would be cheating, wouldn't it?
