Date: Sept. 27, 2026 Participant: David Carballo #13628 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Midrace Rhythm Fades Late but Holds On for a Solid Finish David Carballo completed the Boulderthon Marathon in 4:18:47, an average pace of 9:52 per mile, placing 504th among men and 103rd in the men's 25-29 division. David opened conservatively with a 10:18 first mile before settling into a strong rhythm. His standout stretch came between miles 3 and 11, where he covered eight miles in roughly 9:02 per mile pace, tightening his overall pace from 9:50 to 9:15 per mile. That effort held largely steady through mile 20, before the final six miles slowed into the 11- to 13-minute range, nudging his cumulative pace back up to 9:53 by the finish. Given Boulder's elevation above 5,000 feet, the sustained middle miles stand out as the strongest phase of his race.
