This past weekend, I took and afternoon and went to the beach with some friends. It was really a lovely day. Sunny but not too hot. This trip actually replaced a long run I was supposed to do.
The water was a little chilly, but I still got in a few times. I even got to play frisbee a little. I think with those two things I'll consider it a cross-training day. Of course there was lots of laying in the sun, also, and even a little drawing.
