Last weekend I biked 17.21 KM with an average speed of close to 25 K/HR. The temperature was below 10 degrees.*
Or, last weekend I biked a measly almost-11 miles at around 15 MPH, and it was almost 50.
Take your pick. I know which one *I* like better ;)
Yup. That's it. I'm switchin' to metric.
*None of this will sound terribly impressive if you're either A) not from the 'States or B) into randonneuring, which measures everything in metric anyway.
