Date: Sept. 27, 2026 Participant: Emma Odonovan #11688 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Miles Give Way to a Hard-Earned Finish Emma Odonovan completed the marathon in 4:20:45, an average pace of 9:57 per mile. Her race built patiently: the first 18 miles clicked by between 9:15 and 9:32 per mile, a long stretch of even, controlled running before the effort caught up with her over the final 10K, where mile splits eased into the 10:4511:30 range. A closing mile back at 10:47 showed she still had a gear left for the run down to the Pearl Street Mall. That opening 18-mile stretch stands as the strongest running of her day, holding within a 17-second pace band despite Boulder's elevation above 5,000 feet. The 2026 course itself carried nearly 400 fewer feet of climbing than in prior years, a redesign that likely helped sustain that rhythm through the middle miles before the accumulated distance told late.
