Apparently, I ride a lot faster than I think I do. My wife had her bike computer going today, and clocked us at 34 km/h on the flats, just cruising along. Coasting down the hill, she says we hit 68, but I doubt it. I think 48 is more realistic. I took a reading one time with my Garmin Edge, so I'll check that. Other than that, the ride in was a balmy 12C and calm with brilliant sunshine. Nice.
