Date: Sept. 28, 2025 Participant: Ashley Sullivan #26956 Race: 2025 Boulderthon Half Marathon Distance: 13.1 miles Weather: Perfect running weather with temperatures in the 50's to 70's and nice cloud cover

Consistent but Gradual Slowdown Ashley completed the 2025 Boulderthon Half Marathon with an elapsed time of 2:40:47, maintaining an average pace of 12:16 min/mile. Throughout the race, consistency in early splits was noticeable. For example, the first three miles had consistent pace splits close to 10 minutes per mile. Despite this, she notably slowed down from mile 7 onward, with mile 7 recording a split pace of 27:39 min/milethe slowest of the race. An analysis of her splits reveals an inconsistent pacing strategy. Her initial strong start can be a focal area, as reducing slowdown in latter miles could improve overall time. By examining pacing through mile 6, where the split was 11:22 min/mile, maintaining this consistency could yield better results. Encouragingly, she managed a strong finish with improvements in miles 12 and 13, achieving sub-11 min/mile splits. Focusing on maintaining consistent pacing and slightly increasing endurance would likely enhance future performances.
