Steady Pace Through 5 Miles Before a Late Fade Darlin Diaz Velazquez finished the 2026 Boulderthon 10K in 53:23, an 8:36 min/mile pace, placing fifth in the F 15-19 division. Her race stayed tight through the first five miles, with mile splits ranging between 8:08 and 8:38, keeping her cumulative pace steady between 8:22 and 8:38 min/mile. Mile five, covered in 8:08, stood out as her fastest stretch of the race. The final mile slowed to 9:39, pulling her overall pace to 8:36 by the finish. With Boulder sitting above 5,000 feet of elevation, holding that early consistency for five miles was a solid effort before the late dip.
