Date: Sept. 27, 2026 Participant: Marcos Tilkian #23095 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start, Steady Finish at Altitude Marcos Tilkian finished the half marathon in 1:40:31, placing 380th overall and 303rd among men out of a field of 7,223. His effort held together well across 13.1 miles at elevation. Tilkian's race opened fast and even, covering the first five miles in roughly 36:48 at a 7:21 pace, a stretch that stayed remarkably consistent mile to mile. The middle miles eased slightly, with pace drifting into the high 7:00s and low 8:00s through mile 11, before he closed strong, dropping back to a 7:21 split in mile 12. Given Boulder's elevation above 5,000 feet, that early consistency and late rebound point to well-managed effort throughout the race.
