Date: Sept. 27, 2026 Participant: Dan Guilfoyle #25954 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Half Marathon Effort Holds Firm Through the Back Half Dan Guilfoyle completed the half marathon in 2:05:44, an overall pace of 9:35 per mile. He opened with his fastest running of the race, covering the first two miles in roughly 9:23 pace each, then settled into a steady rhythm through the middle and closing miles, holding between 9:27 and 10:16 per mile from mile six onward. His strongest full mile came late, a 9:07 split at mile twelve, showing he still had gas left before the finish on the Pearl Street Mall. That stretch through miles nine and ten lines up with the course's lululemon Power-Up Zone, positioned around mile 9.5 of the half a boost that may have helped him steady his pace before the closing miles. Given the consistency shown across the second half, he might consider a slightly more even effort in the opening miles next time to bank a bit more energy for the finish.
