Date: Sept. 27, 2026 Participant: Alexandra Deneve #13618 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Consistent Middle Miles Anchor a Steady Marathon Finish Alexandra Deneve completed the 2026 Boulderthon Marathon in 4:39:22. After settling in around an 11:00 min/mile pace early, she found her rhythm through the heart of the race, holding between 9:54 and 10:37 min/mile from miles 15 through 21 the most consistent stretch of her day. That effort gradually eased over the closing miles as fatigue crept into her pace, finishing on the Pearl Street Mall in downtown Boulder. Near mile 22.5, close to where the lululemon Power-Up Zone sits on course, her split slowed to 11:21 as the late miles took their toll. Racing at Boulder's altitude of over 5,000 feet, her ability to hold sub-10:30 pacing for six consecutive miles stands out as the strongest segment of her race.
