This Sunday I run my 'for the shirt' half. Hubs & Thing 1 are running too. Thing 1 thinks he can beat dear ol Dad. He can, but Dad has been messing with his head for the last week or so & may succeed in psyching him out.
It is November. There is frost on the ground. I have to wear pants to run. Sigh.
What is your transition temperature? When do you give in and put away your shorts or skirts?
