Date: Sept. 27, 2026 Participant: Zack Tripp #23004 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Start Gives Way to a Gritty Finish Zack Tripp completed the 2026 Boulderthon Half Marathon in 1:43:54, an average pace of 7:55 per mile. That's a bit off his 2025 result of 1:40:22 (7:39 pace) at the same event. Tripp's race unfolded in two distinct halves: he clicked off the first five miles between 7:36 and 7:48, settling into an early rhythm well under 7:45 elapsed pace. From mile 6 onward, the pace eased gradually, with miles 8 through 11 landing between 8:03 and 8:31, before he closed with a strong 7:50 final mile his fastest mile-plus stretch after the early going. That first five-mile stretch stands as the highlight of his day, holding sub-7:45 pace through downtown Boulder's early miles at altitude above 5,000 feet.
