Date: Sept. 27, 2026 Participant: Seth Robinson #23147 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace, Strong Finish Through the Half Seth Robinson completed the 2026 Boulderthon Half Marathon in 1:50:55, holding an overall pace of 8:28 min/mile across the 13.1-mile course. Robinson's mile splits stayed remarkably tight throughout, ranging from 8:03 to 8:52, with his cumulative pace never drifting beyond a few seconds of 8:30 min/mile from start to finish. That consistency paid off late: his final mile came in at 8:04, one of his fastest of the race, showing strong control in the closing stretch. With the finish line on the Pearl Street Mall in downtown Boulder, a city sitting above 5,000 feet, this kind of even effort reflects sound pacing discipline. If there's an area to explore next time, it might be pushing the middle miles slightly harder to match that strong finishing kick.
