Date: Sept. 27, 2026 Participant: Corey O'Keefe #42018 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers a Steady 5K Corey O'Keefe finished the 2026 Boulderthon 5K in 30:22. Her race built momentum through the middle mile before settling in for the close: mile one came in at 9:28, mile two dropped to 8:28, and the final mile eased back to 11:15. That second mile was her standout stretch of the day, the pace she carried near downtown Boulder before finishing on the Pearl Street Mall. Running the race at Boulder's altitude above 5,000 feet, O'Keefe navigated the early-morning 7:45 AM start with a well-managed pace, showing her quickest gear right in the heart of the course.
