Date: Sept. 27, 2026 Participant: Alynna Phouthakhio #21570 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Start Gives Way to a Gradual Fade Over 13.1 Miles Alynna Phouthakhio finished the half marathon in 2:51:22, an overall pace of 13:04 per mile. Her opening three miles were her strongest stretch, covering that distance in 33:24 for an 11:08 per mile pace, before the effort settled into a steadier decline through the middle and closing miles, finishing with a final-mile pace of 13:05. The race unfolded as a gradual climb in cumulative pace from a brisk 10:58 opening mile to just over 13 minutes per mile by the finish, reflecting a strong early rhythm that eased over the back half. Boulder's elevation, over 5,000 feet, offers useful context for pacing at this event, and Phouthakhio's early-mile speed suggests a runner comfortable pushing the pace before settling in for the long haul to the Pearl Street Mall finish.
