Strong Start Fuels a Top-2% Finish Tanner Gasow crossed the line in 1:27:07, placing 99th overall and 87th among men out of the field of 7,223. That result lands him in the top two percent of all participants. The race unfolded in two distinct halves. Through the first six miles, Gasow was locked into a tight, efficient rhythm, covering that stretch in 37:49 an average pace of 6:18 per mile that was the fastest sustained stretch of his race. The middle miles eased slightly, with pace settling into the 6:497:21 range between miles 7 and 10, before he tightened things back up over the closing 5K, holding steady in the 6:466:51 range to the finish. Given that Boulder sits above 5,000 feet, the early pace stands out as a strong foundation for the overall result.
