From Saturday. Trying out a new route. I dont' think there was a continuous flat stretch more than a few hundred meters. Very rough roads. Got lost a few times, had a nice stretch on gravel. Took it easy mostly because I haven't done a ride around 5 hours in some time.
The garmin had some problem and didn't register the first stretch, thus the discrepancy in the start/end location and also the avg. speed and moving avg. speed.
