Date: Sept. 27, 2026 Participant: Clay Peternell #31278 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace, Strong Finishing Kick Clay Peternell completed the 2026 Boulderthon 10K in 58:44, an overall pace of 9:28 per mile. His race settled into a consistent rhythm through the middle miles, holding between 9:32 and 9:46 per mile from mile one through four, before finding his best stretch of the day: mile five, covered in 8:50, his fastest mile of the race. That surge set up a strong close, as Clay carried the momentum into the final miles to reach the Pearl Street Mall finish. Splits show the effort paid off late, with his overall position improving sharply by the finish line. Running at Boulder's altitude of over 5,000 feet, Clay's pacing discipline across the back half of the course stood out as the defining feature of his race.
