Date: Sept. 27, 2026 Participant: Erik Osterholm #20355 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Closing Miles Power a Near-Repeat Performance Erik Osterholm finished this year's half marathon in 1:35:20, just 40 seconds off his 1:34:40 from last year's race. His pacing followed a similar arc: a brisk opening five miles near 7:15 pace, a dip through mile six, then a steady middle stretch before a strong close. The final three miles were his best of the day, covering miles 11 through 13 in 20:40 a 6:53 per mile pace, well under his overall average. That surge came right around the lululemon Power-Up Zone near mile 9.5, suggesting the boost carried him through to the finish. Given Boulder's elevation above 5,000 feet, holding that closing pace stands out as the highlight of his race.
