Date: Sept. 27, 2026 Participant: Charles Mildrum #10612 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Anchors a Boulder Marathon Finish Charles Mildrum completed the 2026 Boulderthon Marathon in 3:56:50, averaging 9:02 per mile across the 26.2-mile course that finishes on the Pearl Street Mall. His race showed two clear phases: a controlled opening through the first 13 miles, followed by a gradual fade over the back half as splits stretched from the 9:00s into the 10:00-12:00 range by the final miles. His standout stretch came in the first 13 miles, covered at a steady 8:08 average pace, the fastest sustained running of his day. Passing the lululemon Power-Up Zone near mile 22.5, his pace had eased to 9:27 for that split, part of the later slowdown that runners often see at Boulder's mile-high elevation.
