I wasted time quailing over whether I wanted to leave my nice warm house and run when it was 34 degrees out, when I know that thirty-four degrees is perfectly fine for a run. Wear a hat, fingerless gloves, a light jacket, sports bra and a light long-sleeved t-shirt, leggings and running pants, socks, and shoes, you'll be cold for the first block and plenty warm for the rest of the run.
So I didn't get out until 7:30 and I have to be in the shower by 8:00, I set a timer for fifteen minutes and went. I got to one and a quarter miles. The thing is, you know that it took you fifteen minutes to get to where you are; it'll take you fifteen minutes to get back at the same pace, so no lollygagging on the way back. So I ran my whole run. A 12 minute mile is still not spectacular, but it's a minute and a third faster than I was doing—
run 2.5 miles, 30 minutes, 12 min/mile
