Date: Sept. 27, 2026 Participant: Rira Rudnick #24105 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Early Miles Give Way to a Tougher Back Half Rira Rudnick completed the Half Marathon in 2:44:58, an overall pace of 12:35 per mile. Her opening six miles were her strongest stretch, covering that ground in 1:09:45 for an average of roughly 11:37 per mile, keeping her cumulative pace under 11:40 through the first half of the race. From there, the pace eased steadily, with cumulative time climbing from 11:46 per mile at mile 7 to 12:36 per mile by the finish, reflecting a gradual fade rather than a sudden drop-off. Boulder's elevation, sitting above 5,000 feet, adds a layer of difficulty to any distance run through downtown streets. Rudnick's race, finishing on the Pearl Street Mall, showed a well-managed front half before the closing miles slowed. Working on sustaining that early rhythm a bit longer could help even out the pacing in future efforts.
