Date: Sept. 27, 2026 Participant: Henry Flanagan #23263 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Powers a Strong Half Finish Henry Flanagan completed the 2026 Boulderthon Half Marathon in 1:36:43, an average pace of 7:22 per mile. His opening mile was his quickest, clocked at 6:58, and his cumulative pace held in the 7:107:25 range for the bulk of the race before he closed with a strong final mile of 6:50, his fastest full-mile split since the race's start. Flanagan's most efficient stretch came in miles 1-6, where he covered the distance while holding his cumulative pace under 7:15 per mile. Mile 11 was his slowest of the race, at 8:04, but he responded well, dropping back down to 7:16 the following mile. Running at over 5,000 feet of elevation, Flanagan's ability to rebound after that dip and finish strong reflects well on his overall pacing and endurance across the course.
