Date: Sept. 27, 2026 Participant: Brian Rich #27550 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Negative Split Surge Seals a Top-10 Finish Brian Rich ran 1:10:13 to finish 6th overall and 6th among men in the 2026 Boulderthon Half Marathon, a result that lands in the top slice of a 7,223-person field. Rich's pacing stayed remarkably tight through the middle miles, holding between 5:18 and 5:24 average pace from mile 2 through mile 11 despite a slight softening near miles 7-8 (5:31, 5:37). He answered with the race's best full-mile stretch late, splitting 5:02 for mile 12 before closing in 5:10, a strong final surge that pulled his overall average back down to 5:21 per mile. Given Boulder's elevation above 5,000 feet, that late-race quickness stands out as the highlight of the effort.
