Date: Sept. 27, 2026 Participant: Ronan Mcnulty #30158 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start Fades Into a Steady Grind Ronan Mcnulty completed the 2026 Boulderthon 10K in 59:55, an overall pace of 9:39 per mile. He opened with his fastest mile of the day, 8:28, and held sub-9:00 pace through the second mile before settling into a gradual decline, closing with a 10:59 final mile. That opening mile stood out as the clear high point of the race, showing the sharpest turn of speed across the 6.2-mile course. The steady lengthening of each split thereafter suggests an option worth exploring: banking a touch less early speed to hold pace more evenly through the back half. Given Boulder's elevation above 5,000 feet, the effort required to sustain that early pace adds useful context to the day's steady fade.
