Date: Sept. 27, 2026 Participant: Ryan Stewart #13508 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Start Gives Way to a Grinding Back Half Ryan Stewart covered the Boulderthon Marathon in 4:18:24, an average pace of 9:51 per mile. His opening eight miles were the highlight, clicking off in the 8:108:20 range and pushing his cumulative pace as low as 8:11 by mile four. From there, pace held steady near 8:358:45 through mile eighteen before eroding steadily over the closing miles, with cumulative pace slipping to 9:51 by the finish as the final 10K brought the race's slowest sustained running. Finishing on the Pearl Street Mall in downtown Boulder, Stewart tackled a course shaped by the city's altitude above 5,000 feet. Given the strength of his opening third, there may be room to experiment with a slightly more conservative early pace to help sustain that rhythm deeper into the back half.
