It was warm but not that hot here. It was about as warm as Sunday's ride, which felt a lot better. That one averaged 15.6 mph, but it was also 3x as long.
Could be accumulated exercise stress - I did over 150 miles last week, rode 5 days, versus the usual 130-140, including a longer ride on Sunday. But that was after a week where I rode only 52 miles (vaccine effects + destroyed tire on Sunday ride). My HR as I sit here is still in the mid 40s, which is pretty much normal for me.
Anyhow, I'll see how today goes.
