Steady Early Pace Gives Way to a Tougher Back Stretch Isaac Henry finished the marathon in 4:14:16, averaging 9:42 per mile. His race showed two distinct halves: from mile 1 through mile 18, he ran with remarkable consistency, holding paces between 8:16 and 8:58 and reaching the 18-mile mark in 2:34:56 (8:36/mile average). From mile 19 onward, his pace eased steadily, climbing into the 9:1614:53 range through the final miles before closing with a 12:32 last mile. That opening 18-mile stretch stands as the highlight of the day nearly identical splits mile after mile, a sign of well-managed early pacing. Notably, his slower stretch between miles 22 and 23 came right around the lululemon Power-Up Zone, positioned near mile 22.5 of the marathon course. Coming off such a smooth first two-thirds, Isaac may find value in working on late-race durability past that point in future efforts.
