Date: Sept. 27, 2026 Participant: Karina Cardie #42098 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers a Solid 5K Finish Karina Cardie, 24, of Broomfield, completed the 2026 Boulderthon 5K in 31:50, an overall pace of 10:16 per mile. Her race shape showed a clear surge in the middle: after opening in 10:30 for the first mile, Cardie dropped to 8:54 for mile two her fastest mile of the race before easing to 11:24 to close things out. That middle-mile push was the standout stretch of her day, showing a strong gear when she found her rhythm. With the overall effort settling in just past the 10K/mile mark, there's room to explore holding that faster middle pace deeper into the race next time, an approach that could smooth the closing mile. Boulder's elevation, sitting above 5,000 feet, adds context to the effort behind that finishing time.
