Date: Sept. 27, 2026 Participant: Felipe Bustios #32013 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Through Boulder's 10K Highlighted by a Strong Fifth Mile Felipe Bustios finished the 2026 Boulderthon 10K in 59:58, averaging 9:40 per mile across the field of 3,071 entrants. His mile splits show a race that tightened in the middle before finding a rhythm: an opening mile at 9:24, holding near 9:30-9:40 through mile three, a dip to 10:48 in mile four, then a sharp rebound to 8:47 in mile five his fastest mile of the day before closing at 9:51. That fifth-mile surge stands out as the clear high point of the run, showing a strong final push after the slower fourth mile. Racing at Boulder's altitude of over 5,000 feet, Bustios' consistent pacing across the back half reflects solid course management down to the finish on the Pearl Street Mall.
