Sometimes, my spring commutes are like that; 38 in the AM and 75 or even 80 on the way home. When I was teaching, and left for work at 5:45 on the bike, I remember a couple of days going in wearing full thermal winter gear and coming home in a sleeveless jersey and shorts.
It is beautiful out today. I was in a bad mood as all of the members in my women's support group cancelled this morning, so off I went to the grocery store and then after lunch, I went out for a very short ride. I really should be resting today, as I've done lots of muscle work this week, but it's 60 degrees at the end of November! My assessment of my body was correct, so I rode for about 30 minutes, got some fresh air, and now I feel very sleepy. Need to wake up, so I don't fall asleep babysitting my granddaughter tonight.
