Midrace Surge Powers a Steady Marathon Effort Carson Hart completed the 2026 Boulderthon Marathon in 4:27:48, averaging 10:13 per mile. He opened in the 10:0010:30 range through the first ten miles, then found his best rhythm in the middle of the race before easing pace over the closing miles, finishing with a 10:14 per mile cumulative average. Sustaining that midrace tempo a bit longer could offer an even stronger finish next time. His fastest stretch came between miles 10 and 13, where splits of 8:49, 9:28, and 9:16 pulled his cumulative pace down from 10:06 to 9:53 per mile the strongest mile-plus segment of his race. He closed on the Pearl Street Mall in downtown Boulder, on a course that starts and finishes above 5,000 feet of elevation.
