Date: Sept. 27, 2026 Participant: Julian Martinez #10205 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fades Under Late-Race Fatigue Julian Martinez completed the marathon in 4:30:43, an average pace of 10:19 per mile. His race showed a clear split in execution: through the first 9 miles he covered ground at 9:06 per mile, holding that rhythm efficiently across the opening third of the course. From there, elapsed pace slipped steadily, reaching 9:46 by mile 21 and continuing to erode through the closing miles, finishing at a 10:20 per mile average by mile 26. That opening 9-mile stretch stands out as the strongest sustained running of the day, built on a string of miles in the 8:499:23 range. The final 10K told a different story, with per-mile splits climbing into the 12- and 13-minute range as the effort wore on. Running at Boulder's altitudeover 5,000 feetadds a physiological layer to that late fade worth noting as context for the overall effort.
