Date: Sept. 27, 2026 Participant: Clare Lillie #41671 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Surge Through the Middle Mile Anchors a Solid 5K Clare Lillie finished the 2026 Boulderthon 5K in 22:52, an overall pace of 7:22 per mile. Her race built momentum early: an opening mile of 7:21 gave way to a sharp second-mile split of 6:21, the fastest mile of her race, before easing to 8:18 over the closing mile. That middle-mile surge shows a runner comfortable pushing pace mid-race, with the final stretch settling back toward her overall average. Given the strength of that second mile, Clare might look at how to carry more of that speed into the closing mile next time a small tweak that could sharpen an already well-paced effort. Boulder's elevation, over 5,000 feet, adds context to any 5K effort run through downtown Boulder, finishing on the historic Pearl Street Mall.
