Steady Pace Through Five Miles Before a Late Fade Henry Arias finished the 10K in 51:33, placing 210th overall and 143rd among men in a field of 3,071. Arias opened quickly, covering the first mile in 7:39, the fastest split of his race. He settled into a consistent rhythm through the middle miles, holding between 8:00 and 8:22 pace from mile two through mile five, a stretch that kept his overall position stable in the low 200s. The final mile slowed to 9:22, the slowest of the day, as cumulative pace crept from 8:05 at the five-mile mark to 8:18 by the finish. Running at over 5,000 feet of elevation in Boulder, Arias's early consistency through the race's midsection stands out as the strongest phase of his effort.
