Date: Sept. 27, 2026 Participant: Olivia Bosse #27784 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace, Strong Finish Olivia Bosse ran a consistent 1:49:17 half marathon, holding an 8:20 per-mile pace from start to finish. Her splits stayed tightly banded between 8:08 and 8:37 for all 13 miles, showing no significant fade over the second half of the race. Her sharpest mile came early, a 8:08 split in mile two, and she closed strong with back-to-back miles under 8:15 in miles 12 and 13. Running at Boulder's altitude of over 5,000 feet, Bosse's even effort across the full 13.1 miles reflects well-managed pacing on a course that offers little room for error at that elevation. With splits rarely drifting more than 15 seconds from her overall average, there's little to adjust here any future gains would likely come from pushing the middle miles closer to her early pace.
