Date: Sept. 27, 2026 Participant: Brandon Martinez #12235 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fast First Half Fades Into a Grinding Final 10K Brandon Martinez, 23, of Littleton, finished the marathon at the 2026 Boulderthon in 4:33:57, an overall pace of 10:27 per mile. His race opened briskly, holding between 9:30 and 10:10 per mile through the opening miles before locking into his best stretch, miles 9 through 14, averaging roughly 9:20 per mile. That effort held cumulative pace under 9:35 per mile at the halfway point. The back half told a different story: mile 18 slipped to 10:49, and by miles 19-25 he was running between 11:31 and 13:16 per mile, pushing overall pace out past 10:20. That stretch included the lululemon Power-Up Zone near mile 22.5, where his elapsed time had just crossed 3:41. Running at altitude in Boulder, over 5,000 feet, on a marathon course with 603 feet of net gain, his even effort into the closing miles is worth building on.
