Date: Sept. 27, 2026 Participant: Claudia Renteria #41960 Race: 2026 Boulderthon 5K Distance: 3.1 miles

A Fast-Finishing Middle Mile Powers the Pack Claudia Renteria completed the 2026 Boulderthon 5K in 30:16, an overall pace of 9:45 per mile across the 3.1-mile course. Her race built momentum through the middle distance: after opening in 11:55 for the first mile, Renteria surged to a 7:35 second mile, the fastest stretch of her race, before settling into a 9:45 closing mile. That middle-mile drop marked her strongest running of the day, pulling her cumulative pace down from 11:55 to 9:44 by the two-mile mark. Given Boulder's elevation above 5,000 feet, that surge stands out as a notable push through the heart of the course before finishing on the Pearl Street Mall in downtown Boulder.
