Date: Sept. 27, 2026 Participant: Misael Luna Ibarra #11084 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fades Late but Finishes Strong Misael Luna Ibarra completed the 2026 Boulderthon Marathon in 4:20:03, an average pace of 9:55 per mile. Misael ran a disciplined opening, covering the first 10 miles in 8:24 pace and holding 8:45 pace through 18 miles a well-executed front half. The middle miles from 19 to 26 gradually slowed, with mile 21 (13:19) and mile 24 (13:36) marking the toughest stretches of the day, before a strong final mile brought the pace back down to 11:50. The first 10K, split around 8:04-8:24 pace, stood out as the fastest sustained stretch of the race. Given that Boulder sits above 5,000 feet, this opening effort reflects solid pacing execution before the marathon's demands caught up over the closing miles.
