Date: Sept. 27, 2026 Participant: Kayla Mackel #20496 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Start, Strong Finishing Kick Through Downtown Boulder Kayla Mackel completed the 2026 Boulderthon Half Marathon in 3:16:48. She opened with her fastest miles of the day, covering the first mile in 10:54 and holding an 11:02 pace through mile two. The middle miles brought a gradual, steady decline in pace, with mile six clocking 16:46, before settling into the 16-17 minute range for much of the back half. Her final mile, mile 13, ticked back down to 16:22, closing out the race with one of her stronger stretches after the tougher middle section. Boulder's elevation, sitting above 5,000 feet, adds a layer of difficulty to every stride at this event. Mackel's ability to close with a sub-16:30 mile late in the race, after a demanding middle stretch, speaks well to her pacing discipline. Runners looking to build on this result might consider working on maintaining mid-race pace consistency in future training blocks.
