Date: Sept. 27, 2026 Participant: Marissa Carrillo #32799 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Miles Build to a Strong Finishing Kick Marissa Carrillo completed the 2026 Boulderthon 10K in 59:48, an average pace of 9:38 per mile. Her opening miles held remarkably consistent, easing from 9:40 to 9:35 through the first three miles before dropping further to 9:28 and then 9:00 in mile five her fastest full mile of the race. The final mile eased back to 10:20, a natural settling after that surge, closing out a race shaped by a patient build and a strong middle push. Boulder sits at over 5,000 feet of elevation, a notable backdrop for Carrillos sub-10-minute mile late in the race. Her pacing pattern, tightening steadily before that fifth-mile breakthrough, reflects a well-managed effort across the distance.
