Date: Sept. 27, 2026 Participant: Jack Mcguffee #10352 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Opening Miles Give Way to a Tough Back Stretch Jack Mcguffee finished the marathon in 4:33:40. Through the first 17 miles he ran a steady, well-controlled pace, covering that stretch in roughly 9:04 per mile with only minor fluctuations. From mile 18 onward the pace slowed considerably, with several miles drifting into the 12-14 minute range before a final surge brought him home. Running at Boulder's altitude of over 5,000 feet adds a layer of difficulty to any marathon effort, and Jack's early pacing showed he handled it well before the fatigue of the closing miles set in. The lululemon Power-Up Zone near mile 22.5 arrived right in the middle of his slowest stretch a good marker for where an extra mental lift could help next time. Overall, the front-half execution stands out as the strength of this race.
