Consistent Early Performance with Slower Second Half Esmeralda Mora, age 37 from Aurora, CO, completed the 2025 Boulderthon Marathon in a time of 4:05:38, averaging a pace of 9:22 min/mile. Her performance showed strong consistency in the first half, with split paces hovering around the 8:13 to 8:31 min/mile range until mile 7. She had notable splits at mile 5, where she improved her rank significantly, moving to 190th place overall, and then transitioned into a slower pace in the latter half of the race. In the latter miles, her pace gradually slowed, notably with a dramatic increase to 12:31 min/mile pace at mile 21. Despite the deceleration, Esmeralda maintained her position within her division, finishing 14th out of 120 women in her age group. Continued focus on conditioning could help improve endurance in the marathon distance, preserving the pacing consistency seen in the earlier segments of her race and potentially improving her finish time.
