Date: Sept. 27, 2026 Participant: Danielle Acosta #20428 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing With a Strong Closing Kick Danielle Acosta opened quickly, covering her first mile in 8:27 before settling into a rhythm that held between 7:47 and 8:09 per mile through the 10-mile mark. A dip to 9:09 in mile 11 briefly slowed her cumulative pace, but she answered with 8:16 and 8:06 miles to close, finishing in 1:47:51 for an overall pace of 8:13 per mile. Her strongest stretch came from miles 3 through 5, where she clicked off times of 8:01, 7:59 and 7:47 her fastest sustained running of the day. That effort came at Boulder's altitude of over 5,000 feet, adding weight to the consistency she showed across the middle miles. She carried that composure to the finish on the Pearl Street Mall in downtown Boulder, capping a well-managed race from start to finish.
