Date: Sept. 27, 2026 Participant: Pei Zhi Lin #26732 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start, Stronger Finish Pei Zhi Lin completed the half marathon in 1:49:19, an 8:20/mile pace. Her race opened briskly, with a 7:27 first mile, before settling into the 8:00s through the middle miles as elapsed pace crept from 7:59 to 8:23 by mile 12. She closed with a 7:52 final mile, the fastest of the back half, pulling her cumulative pace back down to 8:20 at the line. The half marathon in Boulder a city sitting over 5,000 feet in elevation runs a course with net elevation gain cut nearly 50% in its most recent redesign. Lin's pacing pattern, a fast opening mile followed by a gradual settle and a sharp closing kick, reflects a race managed well from start to finish, with plenty to build on for pacing the middle miles more evenly next time.
