There have been plenty of sub 30 degree and windy days, but today was the first this year that was sub 20 degrees and windy.
I have been regularly hitting my tempo runs in the 6:15-6:20 range. Today I went out and my legs struggled to pick up the pace and I ended up averaging 6:40.
I am thinking maybe it was more of a psychology thing. Anyone else experience this in colder than normal days?
