Strong Start Sets Up a Late-Race Fade Isabel Berrio finished the 10K in 57:58, an average pace of 9:21 per mile. She opened briskly, covering the first two miles in 8:54 and 8:55, before settling into the high 9:20s through miles three and four. A strong rebound in mile five, clocked at 8:51 her fastest mile of the race showed she still had gas in the tank, before the pace eased to 10:27 over the closing mile as she brought it home. Boulder sits at over 5,000 feet of elevation, a backdrop worth noting for any runner tackling the course. Given the rebound in mile five, Isabel might consider working on maintaining that rhythm a bit longer next time, turning a strong mid-race surge into a stronger finish.
