I can relate, recently I rode a 36 mile loop that I ride quite often, the entire time I felt as if I was slow, really slow, got home and downloaded the data, and found it was my fastest ride of the year on that segment. At other times I have felt fast, then downloaded the data to see I didn't have a
PR on a single segment.
