Date: Sept. 27, 2026 Participant: Katelyn Parmelee #11980 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Gives Way to a Gritty Back Half Katelyn Parmelee completed the marathon in 4:20:22. Her opening miles were remarkably even, holding between 8:50 and 9:06 per mile through the first seven miles, before a gradual fade set in over the second half, with several miles slipping past 10:30 and a slowest mile of 11:35 at mile 23. That opening stretch through mile 7, run at just under 9:00 per mile, stood as the strongest sustained running of her day. She passed through the lululemon Power-Up Zone around mile 22.5 as her pace settled into the 10:30-11:00 range, then closed out the final miles toward the Pearl Street Mall finish in downtown Boulder, a course that sits above 5,000 feet of elevation.
