MTB cycling 1:40:00 
I should have gone for a run in the morning. But, I lounged around the house, drank coffee, read the paper, worked on a map project, and worked on the KU class. Then it got hot. I decided a MTB ride would be the best way to get outside without suffering too much.
I biked to the river trail and did some single track. I haven't done that in a while. I felt a bit clumsy. They've made a few changes to the trail. I think that's to address problems with erosion along the river bank from the high water this year.
Fun, but hot.
