Back in March, 2009, I observed that I almost always seem to hit that 1000-mile mark for the year, the second week of March.
I'm premature this year... today I watched the odometer click over 4 digits, to 1000. To the best of my knowledge, March 2 is the earliest ever for that particular milestone. It doesn't really mean anything; it just gives me something to observe and compare. In fact, maybe it's a bit pathetic to be so motivated by my tiny bike computer.
