Date: Sept. 27, 2026 Participant: Leo Acosta #41805 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers Thornton Teen to Solid 5K Finish Leo Acosta completed the 2026 Boulderthon 5K in 30:16, an overall pace of 9:45 per mile. Acosta's race unfolded in three distinct stretches. He opened with a 10:20 first mile, then surged to an 8:30 second mile his fastest of the race before settling back to a 10:24 closing mile. That middle-mile push stands out as the highlight of his race, showing a clear ability to shift gears mid-race. With the finish landing on the Pearl Street Mall in downtown Boulder, a city sitting over 5,000 feet in elevation, Acosta's effort reflects a solid pace swing worth building on. A more even split between miles one and three could help him carry that second-mile speed further next time.
