Date: Sept. 27, 2026 Participant: Erin Lewis #30719 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start Fuels Age-Group Win Erin Lewis crossed the 10K finish in 44:23, good for 66th overall out of 3,071 in the field, 17th among women, and first in the F35-39 division. That result reflects a race built on an aggressive early pace that she worked to sustain through the finish. Lewis opened with a 6:14 first mile, and her opening three miles came through in 19:57 a 6:39/mile pace that stands as the fastest 5K stretch of her race. From there, each mile ticked slightly slower, with her overall pace settling to 7:09/mile by the finish. Given Boulder's elevation above 5,000 feet, holding that early tempo through the middle miles set up the rest of the race well. A touch more even pacing across the back half could be worth exploring next time out.
