Date: Sept. 27, 2026 Participant: Caleb Schreiber #12352 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fuels a Solid Marathon Finish Caleb Schreiber completed the 2026 Boulderthon Marathon in 3:51:02. Through the first 18 miles, he held a steady pace between 7:48 and 8:29 per mile, reaching the midpoint in well under two hours. His fastest stretch came from miles 18, averaging under 7:55 per mile, showing strong early control. The second half saw a gradual pace decline, with miles 1926 slowing into the 9- to 12-minute range as fatigue set in over the closing miles. Boulder's elevation, sitting above 5,000 feet, adds a layer of difficulty to any endurance effort, and Schreiber's ability to maintain sub-8:00 pace through the first two-thirds of the race reflects strong pacing discipline. Should he look to build on this performance, working on sustaining strength through the final 10Kperhaps with more race-specific endurance trainingcould help even out the back-half fade seen after mile 18.
