Consistent Pace with Strong Division Performance David Demer from Castle Pines, CO, completed the 2025 Boulderthon 10K with an overall time of 1:03:16, achieving an average pace of 10:12 min/mile. His performance in the M55-59 division stood out, finishing 10th in his age group. The splits showcase a consistent start with an initial pace of 9:49 min/mile, gradually adjusting to a 10:11 min/mile pace by the end. David demonstrated a promising start, maintaining under a 10-minute mile for the first three miles.

Keep focusing on that consistent pacing strategy, which showed effectiveness in the early miles, to enhance endurance over the full 10K distance.
