Cold: -3F at start. I led for maybe a half mile, then got passed by 2 teens. We stayed in those positions. The first place kid pulled away, but I stayed fairly close to #2 (a 13-year-old boy), and even closed the gap in mile 3, only to get out-kicked at the end.
Perfect pacing for me, all things considered.
