Still, who's counting? Okay, okay, maybe I am. Hoping for some more of that metric magic :)
Actually I've been keeping score another way, too. After each ultra century, I've fashioned a little sticker commemorating the ride. This is what the top tube of my bike looks like now:
Pretty cool, eh? I get a kick out of making a new sticker after each ride, and I like the admiring stares when I ride with my local club on weeknights (the Conejo Valley Cyclists). Yeah, I’m a bit of a ham, what can I say.
