20 miles in temps 20 degrees higher than my last ride, 2 days ago - 88-90 instead of 68-70. Wind also seemed like it was 20 mph higher.
(Actually wind was only 10 mph higher -15-20 instead of 5-10.) And I started out tired.... Still, it was so nice to ride with shorts, a short-sleeved jersey, and sun sleeves instead of tights, base layer, long sleeved jersey, and jacket.
