Date: Sept. 27, 2026 Participant: Jack Jagielski #11008 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Gives Way to a Strong Closing Mile Jack Jagielski completed the marathon in 4:29:26. His opening miles were brisk, clicking off 8:53 and 9:09 paces before settling into a rhythm of roughly 9:009:30 per mile through the middle third of the race. Miles 19 through 23 brought the toughest stretch, with pace slipping into the 12:0013:52 range, but he rallied over the final three miles, dropping back to 10:35, 10:37, and a race-best 8:55 to close things out on the Pearl Street Mall. Running at Boulder's altitude of over 5,000 feet adds its own demand to a marathon distance, and the rebound in that final mile stood out against the fatigue of the previous stretch. Given how well the closing mile came together, incorporating a touch more pacing discipline through miles 1923 could help him carry that late strength further into the race next time.
