On Monday I rolled over 10,000 miles on the Vanilla. Sadly I didn’t have a camera, so you’ll have to take my word for it. An occasion like this is a good time to reckon what my mileage is like over a long period.

vs.

Right now I have 10,030 mi. on the Vanilla and 3516 mi. on the Soma. I know that I’ve ridden 3365 mi. since September 11, 2007, because on that day I rolled over 6666 mi. and blogged about it. 869 days have passed since that day, so I can get weirdly accurate numbers for my aggregate mileage:

This leaves off a few miles I’ve ridden on my newish Kona mountain bike, which I never bothered to fit with a computer. Also, I’ve changed the batteries on both road bike computers, which means there are a few miles off the books for those bikes as well. But really, I can’t imagine I have more than 100–200 mi. unaccounted for.

This year I resolved to ride 100 mi./week, every week, without rolling miles from long weeks into short ones. Which means I have to dig up an extra 44.58 mi./wk.

I can do a wee bit more math, this time less precise. I have previously calculated that, for my weight, and over the hills I usually ride, and at my usual pace, I burn about 550 kcal/hr. riding my bikes. (“kcal” means the same thing as “calories” in general usage.) This lets me reckon the following:

So, and not to put too fine a point on it, the excess mileage I’m making to meet my resolution lets me drink a hard case of New Belgium Fat Tire beer every week, and still lose weight.
