Date: Sept. 27, 2026 Participant: Matthew Spencer #13030 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Miles Give Way to a Hard-Earned Finish Matthew Spencer completed the marathon in 4:28:26. Splits show remarkable consistency through the first 18 miles, holding between 9:13 and 9:45 per mile and settling into a cumulative pace near 9:24-9:25 min/mile by the midpoint. That steady effort carried through mile 18 before the pace eased over the closing miles, with per-mile splits stretching into the 11:49-14:11 range from miles 19 through 23. The final three miles saw a slight rebound, closing with a 10:01 split in the 26th mile. Racing at Boulder's elevation of over 5,000 feet, Spencer's opening 18 miles reflect strong, well-managed pacing on a course that finishes on the Pearl Street Mall. With that opening stretch as a foundation, tightening the pacing gap between the early and late miles could be a useful focus for future long-distance efforts.
