Date: Sept. 27, 2026 Participant: Kari Rivera #32700 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Carries Her Through a Solid 10K Kari Rivera crossed the finish in 1:00:52, an overall pace of 9:49 per mile across the 6.2-mile course. Her race opened strong, clicking off the first mile in 10:12, and she settled into a rhythm that held largely steady through the back half, closing out the final mile in 10:32. That opening mile stood as her most efficient full-mile stretch of the day, a solid foundation for the rest of the run. Racing at over 5,000 feet of elevation in Boulder adds a layer of difficulty to any distance, and Riveras pacing reflects a runner who managed that context well, avoiding any late fade and finishing within a tight range of her early tempo. Building a touch more consistency between the third and fifth miles could be a useful focus for her next 10K.
