Date: Sept. 27, 2026 Participant: Johnny Tomblin #12362 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Gives Way to a Determined Closing Stretch Johnny Tomblin completed the 2026 Boulderthon Marathon in 4:13:57, an average pace of 9:41 per mile. His race showed a strong, even first half miles 1 through 10 held between 8:43 and 9:19 per mile, settling his cumulative pace near 9:03 by the 10-mile mark. From there, effort gradually eased, with mile splits drifting into the 9:40s and eventually the 10:3011:00 range over the final 10K, nudging his overall pace up to its 9:41 finish figure. That opening 10-mile stretch stands as the highlight of the race, run at a full 3540 seconds per mile faster than the closing miles. Around mile 22, near where the course's lululemon Power-Up Zone sits, his pace eased into the high 10:00s a natural point to consider a touch more reserve for next time. The effort came at Boulder's altitude of over 5,000 feet, adding context to the closing miles' toll.
