I rode my morning "non-commute" that covered about 0.6-0.7 of a full round trip commute this morning -- call it a recovery ride.
At least it's a recovery ride until my sweat glands noticed the temperature was 78F at 8:00. That's only about 5 degrees warmer than it's been all week in the morning, but it felt a lot warmer. I remember maybe 10 years back when the temperature never got below 80F for most of the month of July, with dew on the grass every morning so the humidity was 100%. How did I manage?
