Date: Sept. 27, 2026 Participant: Ellie Slattery #27636 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Finishing Kick Seals a Steady Half Marathon Ellie Slattery covered the 2026 Boulderthon half marathon in 1:51:13. Her mile splits held in a tight 8:258:50 band through the middle miles, keeping her cumulative pace steady near 8:358:37 per mile from start to mile 11. The final two miles were her sharpest of the race: 7:59 for mile 12 and 8:01 for mile 13, pulling her overall pace down to 8:29 per mile by the finish. That closing surge came after passing through the lululemon Power-Up Zone near mile 9.5, and it's worth noting given Boulder's elevation above 5,000 feet. Given how well she handled the later miles, working on carrying that same rhythm into the earlier stretch could be a useful focus for her next half.
