Date: Sept. 27, 2026 Participant: Seily Gaucin #30623 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Fast Start Fuels a Steady Finish Seily Gaucin covered the 10K in 1:02:37, an average pace of 10:06 per mile. Her race opened quickly, with a first mile of 8:08 that stood as her fastest of the day, before the pace eased through the middle and closing miles, settling near 11-12 minutes per mile over the final stretch. Boulder's elevation, over 5,000 feet, sets the stage for every finish here, and Gaucin's early pace reflected a strong push through that thinner air before the pace naturally settled later in the race.
