Date: Sept. 27, 2026 Participant: Blythe Sales #27647 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Negative-Split Half Marathon Fueled by a Strong Second Act Blythe finished in 2:03:48, opening with three miles near 10:00 pace before steadily accelerating over the back half. By mile 10 her cumulative pace had dropped to 9:35, and she closed the final 5K in the 9:009:03 range, showing strong control and finishing pace. Her standout stretch came in mile 10, clocked at 8:47, part of a steady descent from mile 7 onward that carried her through the course's later miles the stretch that took the field out past Boulder Reservoir before the return into downtown Boulder. Finishing on the Pearl Street Mall at over 5,000 feet of elevation, Blythe's ability to negative split is a strong foundation to build from for future races.
