Steady Early Pace Fades Slightly Down the Stretch Tariro Goronga finished the 2026 Boulderthon Half Marathon in 1:44:17, averaging 7:57 per mile across the 13.1-mile course through downtown Boulder. Goronga's opening mile came in at 7:15, and he held a strong rhythm through the first 10 miles, hovering between 7:20 and 7:49 per mile of cumulative pace. Miles 7 through 10 saw a gradual easing, with splits settling into the 8:11-8:30 range, before mile 11 slowed further to 9:09. He rallied over the final two miles, closing with an 8:08 and a 7:57 mile to finish strong. His fastest mile-plus stretch came early, through mile 3, when his cumulative pace sat at 7:29 per mile - a mark he'd work to sustain through the rest of the race in Boulder, a city sitting at over 5,000 feet of elevation.
