Date: Sept. 27, 2026 Participant: Brittany Ahern #41921 Race: 2026 Boulderthon 5K Distance: 3.1 miles

A Strong Middle Mile Powers a Steady 5K Finish Brittany Ahern completed the 2026 Boulderthon 5K in 29:06, an overall pace of 9:23 per mile. Her race built through a strong second mile, clocked at 8:02, before easing back over the closing stretch to the Pearl Street Mall finish. Starting at 9:32 for the opening mile, Ahern's pace tightened considerably by the halfway point, dropping her cumulative pace to 8:46 per mile after two miles. That second-mile surge stands as the highlight of her race, a clear gear shift from the opening pace. The final mile came in at 10:33, a natural settling after the faster middle stretch, closing out a well-shaped effort through downtown Boulder, a city sitting above 5,000 feet of elevation.
