Sustained Effort with Mid-Race Surge Araceli Garcilazo completed the 2025 Boulderthon Marathon with a total time of 4:26:42, maintaining an average pace of 10:10 min/mile. Her race performance was notably consistent, with all splits closely aligned around her overall pace. A significant surge occurred between miles 4 and 5, where Araceli improved her position drastically from 1207th to 570th overall with a pace shift to 5:45 min/mile, suggesting strong energy conservation at the start. Araceli's overall placement was 886th among 2678 participants, and she placed 222nd among women and 69th in her F25-29 age division. Noteworthy is her strategic pace drop after the initial surge, balancing endurance with performance across the majority of the course. Consistent times beyond the halfway mark indicate a steady approach. A focus on maintaining even pacing without the need for dramatic surges could positively impact future race outcomes.
