Date: Sept. 27, 2026 Participant: Jada Corby #26545 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Distance Work Through the Back Half of the Course Jada Corby finished the half marathon in 3:49:25. Her opening mile was her fastest of the day at 12:53, and the pace gradually eased through the middle miles, bottoming out with a 20:17 split at mile eight. From there she held a more even rhythm, and mile twelve stood out as her strongest late-race effort at 17:03, a clear pickup from the 20:14 split that preceded it. Corby passed through the lululemon Power-Up Zone around mile 9.5, in the stretch where her mile nine and ten splits ran 20:14 and 19:13. That effort came at Boulder's elevation of over 5,000 feet, adding context to the pacing across the second half of her race. Holding that late mile-twelve surge over a longer stretch could be a useful focus for future half marathons.
