Consistent Success in Division Kristine Leader completed the 2025 Boulderthon Half Marathon with a final time of 1:43:25, maintaining a steady average pace of 7:53 min/mile. Her performance included strong finishes within her division (F55-59) as she secured 1st place. Notably, Kristine showed excellent pacing consistency throughout the race, with most splits within seconds of her overall pace, regardless of minor fluctuations. Although Kristine's final time was slightly slower than her previous 2023 Boulderthon performance (which was completed in 1:42:31 with a 7:49 min/mile pace), she demonstrated resilience by finishing first again in her age division. Her ability to maintain first place despite an increase in total participants (6,546 vs. 3,498) is commendable. Focusing on earlier mile pacing could help match or exceed her previous best.
