Date: Sept. 27, 2026 Participant: Kaori Barnes #25799 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing Carries Her Through Boulder's Back Roads Kaori Barnes covered the Boulderthon half marathon in 2:17:58, holding to a consistent rhythm across the 13.1 miles at just over 10 minutes per mile. Her pace held tight through the first ten miles, dipped slightly into the 11:00s over miles 8 and 9, then rebounded before the finish. Her strongest stretch came in mile 12, clocked at 9:55, the fastest mile of her race, closing with a strong push before the finish. Boulder sits above 5,000 feet, and holding that kind of pace late in a half marathon at altitude speaks to well-managed effort. A slightly steadier middle stretch could smooth the overall progression next time out.
