Date: Sept. 27, 2026 Participant: Emily Hao #31009 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start Fades as Pace Eases Late in the 10K Emily Hao completed the 2026 Boulderthon 10K in 1:01:33, an average pace of 9:55 per mile. She opened with her quickest miles of the race, covering the first two in 8:58 and 8:54, before settling into a steadier rhythm through the middle miles. The closing miles brought a gradual decline in pace, with the final mile landing well off her early speed. Her opening two miles stand out as the fastest mile-plus stretch of the race, showing a confident early rhythm before the effort naturally eased. Boulder's elevation, sitting above 5,000 feet, adds context to any pace shift over a 10K distance. Given how well those first miles moved, Hao might consider working on sustaining that early tempo deeper into future races.
