Pook! Ding-fu!! I knew I was fast Sunday. For the first hour. Then it was average, then labored. The more I contemplated the ride, the more I questioned how good it was. My Garmin threw me a curve. On the downhill leading to 360, it turned itself off. While I immediately turned it back on and made sure it was recording, because it wasn't showing time and mileage, I didn't know if it reset at zero. When I checked all the data, the mileage was correct, thus I accepted the other data.
But, as the old saw goes: if it sounds too good to be true, it isn't. I double-checked the graphs, and there was an absence of the first two climbs, and the downhill. Apparently, some of the data continued, but the time reset itself.
It was a hard workout, discounting the data. We just have to erase the PB designation for the first half.
