It's not just about the temperature difference in the morning; it's about getting the run done so that the rest of the day is free, and especially on the weekend, I never know what plans might pop up that will take away from my running time.
So, yesterday, as you know I did not do my long run in the morning, and I kinda thought I might do it last night. But when friends asked if we wanted to do a game night and order pizza, I didn't have to think twice: friends, pizza, beer, games? Or running? Yeah, the former won out.
And of course, I did not get up early this morning, so that means I've procrastinated enough this weekend that my long run has to be done on Sunday night. Good lord, next weekend I have to get my act together b/c Saturday night is our 4th party (a few days early b/c we all have to work on the 5th -- damn the 4th for falling in the middle of the week!). So, I think I'll spend the day today relaxing and waiting for the cruel sun to set -- then I have 9 miles to log.
