Date: Sept. 27, 2026 Participant: Ashlee Chapman #13389 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Pacing Through Two-Thirds of the Distance Before a Late-Race Fade Ashlee Chapman finished the marathon in 4:40:50, an elapsed pace of 10:43 per mile. Her race settled into a rhythm early: after a brisk opening mile near 10:00, she held mile splits in the 10:20s-10:40s through mile 20, keeping her cumulative pace remarkably flat between 10:19 and 10:32 per mile for that entire stretch. Miles 21 through 25 saw a gradual slowdown, with splits climbing into the 11:00s and peaking at 11:46, before she picked the pace back up over the final mile. Her fastest full mile came at mile 11, clocked at 9:52, a strong surge within an otherwise even middle section. That consistency carried her past the lululemon Power-Up Zone near mile 22.5, a stretch where many runners feel the effects of Boulder's altitude above 5,000 feet, before she closed out the race on the Pearl Street Mall.
