Date: Sept. 27, 2026 Participant: Alden Pennington #27102 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing Anchors a Strong Half-Marathon Close Alden Pennington finished the Half Marathon at 2026 Boulderthon in 2:01:00, averaging 9:14 per mile. Her race opened briskly, with the first four miles ticking off between 8:54 and 9:14, and she held that rhythm through mile seven near 9:05 pace. Miles eight through eleven brought a stretch of slower splits, peaking at 9:51 for mile eleven, before she rallied over the final two miles, closing in 9:08 and 9:07 to bring her cumulative pace back to 9:14. That late surge made miles twelve and thirteen her strongest sustained stretch of the race. Running at Boulder's altitude of over 5,000 feet, Pennington might look to smooth the middle miles next time, carrying more of that early rhythm through to the finish.
