Date: Sept. 27, 2026 Participant: Anna Petr #26712 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start, Stronger Finish: A Top-Tier Half Marathon Debut Anna Petr finished the 2026 Boulderthon Half Marathon in 1:19:19, placing 34th overall out of the field of 7,223 and 5th among women. She opened fast with a 5:44 first mile, held in the 5:50s-6:00s through the middle miles, dipped slightly through miles 7-11 as split times crept toward 6:25, then closed with a strong surgea 5:47 twelfth milebefore finishing at 6:04 pace. That late-race mile stood out as her fastest sustained stretch after the opening mile, showing solid closing strength over the final quarter of the race. Racing at altitude in Boulder, where the 2026 half marathon course was redesigned to reduce net elevation gain by nearly 50%, Anna's ability to rally in the final miles reflects strong control over pacing on a course built for faster overall times.
