Steady Pacing Anchors a Strong Half-Marathon Finish Caleb Keadle covered the half marathon in 1:49:53, an 8:23 min/mile average. He opened briskly, clicking off his fastest mile in the second mile at 7:43, then settled into a steady middle stretch through miles 310, holding paces between 8:13 and 8:47. A mild dip surfaced from miles 7 through 11, before he closed with his strongest sustained stretch of the back half, dropping to 8:18 and 8:12 over the final two miles to finish strong. Racing at altitude in Boulder, sitting over 5,000 feet, Keadles ability to close with two of his quickest miles speaks well of his conditioning down the stretch. That final surge carried him onto the historic Pearl Street Mall for the finish. With this pacing pattern established, a slightly more even middle third could help him carry even more speed into that closing kick next time.
