Date: Sept. 27, 2026 Participant: Christian Chaves #13680 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Middle Miles Anchor a Solid Boulder Finish Christian Chaves completed the marathon in 4:30:46, opening with an 8:50 first mile before settling into a rhythm. Miles 9 through 13 were especially even, holding between 9:31 and 10:01 per mile, showing strong pacing control through the race's midsection. From there, the pace gradually eased through the second half, with the final 10K sliding into the 11:40s and 12:00s per mile before a stronger closing mile at 11:23. Boulder's elevation, over 5,000 feet, adds context to any marathon effort in this race. Chaves' mile 22 split fell right around the lululemon Power-Up Zone near mile 22.5 of the marathon course, a stretch where the pace naturally settled into its slowest phase of the day. Overall, a race built on a well-managed middle stretch, with room to explore holding closer to that rhythm deeper into the closing miles.
