Clear and perfect temps, requiring only a light jacket and shorts. I had a lot of energy and was blazing away for a while but I backed off a bit because I've been really increasing miles (biking and running) recently. I did the get-a-ride-with-wife-and-kids-to-school-then-leave-from-there trek today for 13 miles. I'll zoom home tonight all the way (20 miles), hopefully with a nice tailwind.
There is supposed to be rain and lower temps starting tomorrow and through the weekend.
