Date: Sept. 27, 2026 Participant: Sofia Parra #26789 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Fast Opening Miles Anchor a Steady Half Sofia Parra completed the Boulderthon Half Marathon in 1:53:01, an average pace of 8:37 per mile. Her race showed a clear shape: after opening with four miles between 7:58 and 8:22 her fastest sustained stretch of the day, averaging 8:08/mile through mile four her pace eased through the middle miles, dipping to 9:47 by mile eleven before tightening again over the final two miles to close in 8:50 and 8:41. That mid-race stretch lined up with the lululemon Power-Up Zone near mile 9.5, where her splits were hovering around 8:55-9:00 per mile. Given Boulder's elevation above 5,000 feet, holding sub-8:15 pace early and finishing under 8:40 overall reflects a well-managed effort across the course.
