Date: Sept. 27, 2026 Participant: Adelaide Browning #32999 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Powers a Top-10% Finish Adelaide Browning ran 52:23 in the 10K, placing 240th overall out of the field of 3,071 and 77th among women, while topping the Female 14 & Under division. That result put her ahead of nearly 90 percent of entrants at an event that starts at over 5,000 feet in Boulder. Her mile splits held in a tight band through the first four miles 8:17, 8:30, 8:24, 8:29 before she turned in her fastest mile of the race, a 7:55 fifth mile, the strongest stretch of her day. The final mile eased to 9:11 as she carried that effort to the finish on the Pearl Street Mall. With such consistent early pacing, she could experiment with holding that fifth-mile speed a bit longer in a future 10K.
