Date: Sept. 27, 2026 Participant: Tony Byler #11767 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Holds Steady Before Late Miles Slow the Finish Tony Byler finished the marathon in 4:25:42, an average pace of 10:08 per mile across the 2026 Boulderthon course in Boulder, Colorado. Byler's race showed remarkable consistency through the first 20 miles, holding a steady pace between 9:20 and 10:16 per mile, with his 20-mile split settling at 9:43 per mile a well-controlled effort over a long stretch. The pace eased in the closing miles, with mile 21 slowing to 13:44 before gradually recovering to the 10:2510:41 range through the finish. Given that the 2026 marathon course was redesigned with net elevation gain cut nearly 40 percent, from 982 to 603 feet, and that Boulder itself sits above 5,000 feet, that steady early pacing stands out as the highlight of the day. A slightly more conservative early pace could help sustain that rhythm deeper into future races.
