Date: Sept. 27, 2026 Participant: Adam Robertson #30225 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Anchors a Strong Age-Group Finish Adam Robertson finished the 2026 Boulderthon 10K in 53:01, placing 6th in the M45-49 division. His mile splits held tight through the first three miles (8:45, 8:33, 8:41) before he found another gear, dropping an 8:19 fourth mile and a 7:49 fifth mile his fastest of the race. The final mile eased back to 9:12 as he carried his effort to the line, closing out a well-paced run overall. Racing at altitude in Boulder, sitting above 5,000 feet, Robertson's negative-split middle miles stand out as the highlight of his day. Runners looking to build on this result might consider a touch more reserve early to sustain that mile-five surge all the way to the finish.
