Date: Sept. 27, 2026 Participant: Ian Dioso #25763 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Carries Him Through the Back Half Ian Dioso finished the 2026 Boulderthon Half Marathon in 1:45:11, an 8:01 min/mile pace that placed him 545th overall and 417th among men in the field. His race stayed remarkably even: after an 8:13 opening mile, he held between 7:52 and 8:16 through the middle miles, with only a brief dip to 8:35 at mile 11 before a strong 7:27 mile 12, his fastest full mile of the race, pulled his cumulative pace back down before the finish. That consistency held up even as he passed the lululemon Power-Up Zone near mile 9.5, where his pace was still locked in the low 8:00s. Running at Boulder's altitude of over 5,000 feet, Dioso's ability to close with a sub-7:30 mile after ten miles of steady work stands out as the highlight of his effort.
