Consistent Middle Splits, with Late Race Variability During the 2025 Boulderthon Half Marathon, Sean Swierczewski from Denver showcased a mix of steady pacing and strategic bursts, achieving a finishing time of 2:00:10 with an overall pace of 9:10 min/mile. Notably, the highest split speed was recorded at mile 9 with a split pace of 6:52 min/mile, illustrating potential for strong speed work. Sean's pacing remained fairly consistent, closely ranging around the 9:00 min/mile mark for most of the race.
