This guy ran the first 5k at a 9:55 pace, cut the course by walking north to 10th street, then ran the last two miles at 12:00 pace.

If you look at his photos, he is wearing a baggy cotton t-shirt, baggy basketball shorts, and a coat tied around his waist. Hardly looks like a 1:25 half marathoner.
