Steady Pacing Secures a Runner-Up Age-Group Finish Sarah Erwin covered the 10K in 54:10, an 8:44 per mile average, finishing second in the women's 45-49 division. She built her race with a strong opening mile at 8:12 and held pace within a narrow band through mile five, before easing back over the closing mile. The first two miles were the fastest sustained stretch of her race, clicking off at roughly 8:12-8:13 pace as she settled in early. From there, her mile splits crept upward gradually 8:40, then 8:56 before finding rhythm again at 8:32 for mile five. Running at Boulder's altitude of over 5,000 feet, Erwin's disciplined early pacing gave her a cushion to work with as the race wore on, and her final position among a strong local field reflects that early investment.
