Date: Sept. 27, 2026 Participant: Kari Radke #21480 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Early Pace Fuels Steady Half Marathon Finish Kari Radke finished the Half Marathon in 1:46:49, an 8:09 min/mile average pace, in Boulders 2026 Boulderthon. Her race shape showed a fast start, covering the first six miles at an average pace of 7:52 min/mile before easing into the high-8:00s pace through the middle miles. That opening six-mile stretch stood as her strongest of the day, aided by the relatively gentle early terrain of the reworked half marathon course, which trims net elevation gain to about 203 feet. She rallied over the final two miles, dropping to 7:34 for mile 12 before cruising to the finish on the Pearl Street Mall, a strong close after cresting more than 5,000 feet of Boulder altitude throughout the race.
