Consistent Start, Challenging Finish in Boulderthon Pengfei Li from Parker, CO, demonstrated a strong and consistent start at the 2025 Boulderthon. His early miles were particularly impressive, with a sub-7:30 min/mile pace maintained through the first half. Notably, at mile 5, he achieved a split pace of 7:28 min/mile, improving his position to 87th overall and 8th in his age division. This early phase showcases his solid pacing strategy and competitiveness. However, the latter half of the marathon presented challenges where his pace gradually slowed. Mile 22 saw a distinct drop with an 11:47 min/mile split, leading to a finish with an average elapsed pace of 8:40 min/mile. He concluded the race with a time of 3:47:19, finishing 32nd in the M35-39 division. For future races, maintaining the early pace consistency through the latter stages could enhance his overall performance and standing.
