Date: Sept. 27, 2026 Participant: Andrea Henderson #27242 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing Through the Middle, Strong Closing Surge Andrea Henderson finished the half marathon in 2:00:34, an average pace of 9:12 per mile. Her race unfolded in three phases: a consistent opening 9:009:10 pace through the first four miles, a strong middle stretch, and a late fade before a determined final push. Miles 5 through 7 were her best sustained running, covering that three-mile stretch in roughly 8:51 per mile, anchored by a 8:35 split in mile 6 her fastest mile of the race. After a dip through miles 811, including a 10:03 mile 11, she rallied over the final two miles, closing in 9:34 and 9:10 to finish strong. Racing at over 5,000 feet of elevation, Henderson's ability to hold sub-9:15 pacing for most of the distance, despite the mid-race slowdown, speaks to solid endurance management. Revisiting that strong 57 mile stretch as a pacing template could help smooth out the late-race dip in a future effort.
