Date: Sept. 27, 2026 Participant: Yaseen Khalaf #30799 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Early Speed Sets the Tone Before a Late Fade Yaseen Khalaf completed the 10K in 1:19:19. His opening three miles were the strongest stretch of the race, holding a steady pace between 11:38 and 12:15 per mile and building a cumulative pace under 12:00/mile through the 3-mile mark. The fourth mile slowed to 13:35, and after a brief rebound to 12:16 in mile five, the final mile eased further to 15:02, pulling his overall elapsed pace to 12:47 per mile by the finish. Racing at Boulder's altitude of over 5,000 feet adds a layer of difficulty to every split on this course. Given that context, the consistency Khalaf showed across the first three miles stands out as the foundation of his race. Working on maintaining that early rhythm deeper into the back half could be a useful focus for future 10Ks.
