in just about 4 hours for you the heat will cool off and the sun will start to set! sounds like the Perfect time to pick up that .6 miles! and yuppers I know what you mean - last night as I was logging my ride I saw I had ridden 24.98 miles. .98?? well poop - if I'd been paying more attention I'da picked up that .02 miles to make it an even 25.
