Date: Sept. 27, 2026 Participant: Coltt La Velle #12326 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Rhythm Fades Over Final 10K Coltt La Velle finished the 2026 Boulderthon Marathon in 4:06:41, an average pace of 9:24 per mile. Through the first 18 miles, he held a remarkably consistent rhythm, running each mile between 8:18 and 8:53, settling his cumulative pace right around 8:32-8:34 per mile. That steadiness gave way over the last 8 miles, where his mile splits climbed into the 9:03-13:21 range, pushing his overall pace out to 9:24 by the finish. Running at over 5,000 feet of elevation in Boulder, La Velle's toughest stretch came between miles 21 and 24, where his pace slowed from 10:47 to a 13:21 mile right around where the course passes the lululemon Power-Up Zone near mile 22.5. Sustaining more of that early-race rhythm through the closing miles is worth targeting next time.
