Date: Sept. 27, 2026 Participant: Supansa Kitjaroen #30358 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Opening Mile Sets the Tone Before a Steady Fade Supansa Kitjaroen completed the 10K in 1:29:32, an elapsed pace of 14:26 per mile. Her race opened quickly with an 11:21 first mile, the fastest stretch of her day, before cumulative pace settled into the 12:0013:40 range through the middle miles. The final mile brought the most noticeable slowdown, closing out the distance to the finish in downtown Boulder. Racing at over 5,000 feet of elevation in Boulder, Kitjaroen's early pace stood out against the rest of her race, and revisiting that opening rhythm later in the 10K could be a useful target for her next start at this distance.
