I was supposed to have a late lunch with a friend. I was thinking 1:30-2:00 while I was in Seattle. So I got there, changed into running clothes, and was working a bit. At 12:30 my phone rang and he said he'd be by in 20-25 minutes.
I ran down the hall, went from the 11th to the 4th floor, found a treadmill, and hit it at 5mph at first, then going up to 7mph for most of the run to try and get done quickly.
