Date: Sept. 27, 2026 Participant: Denise Castro Medina #26659 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Carries Steady Half-Marathon Finish Denise Castro Medina completed the half marathon in 3:00:13, an overall pace of 13:45 per mile. She opened briskly, covering the first two miles in 11:30 and 11:27, the fastest mile-plus stretch of her race. From there, her per-mile pace eased gradually through the middle miles, dipping into the 15-16 minute range around miles 7, 8, and 11, before tightening again over the final two miles to 14:15 and 14:10. That closing stretch showed good composure after the tougher middle section, bringing her home with a controlled finish. Castro Medina's race ended where every Boulderthon distance does on the historic Pearl Street Mall in downtown Boulder, a fitting stage for closing out 13.1 miles with two of her steadier miles late in the effort.
