Date: Sept. 27, 2026 Participant: Jack Mcguinn #41893 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Surge Through the Middle Mile Jack Mcguinn crossed the 2026 Boulderthon 5K in 24:25, placing 216th overall and 161st among men in a field of 2,677. That result put him in the race's top 10 percent, a clean, well-paced effort from downtown Boulder. Mcguinn opened with a 7:54 first mile before dropping into a 6:43 second mile, his fastest of the day, before easing to 8:48 over the closing stretch. That middle-mile push was the clear highlight of his race, showing a strong ability to accelerate once settled into rhythm. Running at over 5,000 feet of elevation, Mcguinn's pacing pattern suggests a runner comfortable adjusting effort mid-race; building a bit more evenly off that strong middle mile could help sustain speed through the finish next time.
