Steady Pace Through Halfway, Strong Finish to Close Valerie Jirsa completed the half marathon in 2:19:08, an average pace of 10:37 per mile. She built an early foundation through the first five miles, covering that stretch at a 10:00 per mile pace before a tougher middle section slowed her rhythm. She regrouped over the closing miles, holding pace between 10:01 and 10:45 per mile from mile 8 to the finish on the Pearl Street Mall. The opening five miles stood as the strongest stretch of the race, with each mile landing between 9:49 and 10:17. That opening effort set the tone before the terrain through miles 6 and 7 pushed her pace out to 11:30 and 13:37. Recovering well, she closed with four of the last six miles under 10:45, finishing strong in a city sitting above 5,000 feet of elevation.
