Shaving a Decade of Minutes: A Big Leap Forward Peyton Kling ran the 2026 Boulderthon 10K in 1:01:21, a sharp improvement from her 1:11:03 finish at the same race in 2025 nearly ten minutes faster. Her pace held remarkably steady across the distance, hovering between 9:19 and 10:30 per mile, showing strong pacing control from start to finish. Her standout stretch came in mile five, clocked at 9:19, the fastest mile of her race and a clear surge before the final push. She closed with a 10:30 sixth mile, a reasonable settle after that effort. Running at altitude in Boulder, which sits above 5,000 feet, makes her overall consistency and improvement even more notable. This performance reflects meaningful progress in both fitness and pacing discipline compared to last year's outing.
