Steady Middle Miles Power a Strong Half Marathon Finish Chad Bosel completed the half marathon in 1:43:00, averaging 7:51 per mile. After opening two miles near 7:52 pace, he settled into the race's best stretch between miles 3 and 6, covering that four-mile segment in roughly 7:33 per mile. The pace eased slightly through the second half, dipping to 8:43 for mile 11, before he closed with a 7:48 twelfth mile and held on for the finish. Runners passed the lululemon Power-Up Zone near mile 9.5, right around where Bosel's own pace began to loosen before he rallied late. The race unfolded at Boulder's altitude of over 5,000 feet, a backdrop worth noting given the steady rhythm he sustained through the early and middle miles.
