Strong Start Carries Steady 10K Finish Mia Chen covered the 10K in 54:49, an 8:50 per mile pace, finishing 356th overall out of a field of 3,071. Her race opened fast, with the first two miles clicking off at 8:15 each the strongest full-mile stretch of her day. From there, the pace eased into the 8:409:30 range through miles three to five before tightening back up to 9:11 for the final mile, a sign of solid closing strength after the early efficiency wore off. Running at Boulder's altitude of over 5,000 feet adds a layer of difficulty to any pace, and Chen's early-mile speed reflects well on her fitness heading into the thinner air. Building a bit more even pacing between miles two and four could help her sustain that opening rhythm deeper into future 10Ks.
