Date: Sept. 27, 2026 Participant: Nico Siy #20133 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Carries Through a Steady Half Marathon Nico Siy completed the 2026 Boulderthon Half Marathon in 1:53:01, averaging 8:37 per mile. Siy opened fast, covering the first mile in 7:27 and holding sub-8:00 pace through mile three before settling into a steadier rhythm in the 8:159:30 range for the middle miles. His strongest stretch came early: miles one through three averaged well under 8:00 per mile, the quickest mile-plus segment of his race. The closing miles held firm between 8:52 and 8:56, showing consistent effort as he approached the finish on the Pearl Street Mall in downtown Boulder, a city sitting above 5,000 feet of elevation. A slightly more even pacing plan through the middle miles could help him carry that opening speed further next time.
