Consistent Mid-Race Surge Sadar Castillo maintained an overall steady performance in the 2025 Boulderthon Half Marathon. Notably, he exhibited remarkable consistency in pacing mid-race, especially from miles 4 to 6, achieving split paces of 8:33, 8:15, and 8:08 min/mile, respectively. This surge saw him improve his placing from 886 overall at mile 4 to his best overall ranking of 578 by mile 5. His finishing time was 1:57:01, with an average pace of 8:56 min/mile. In the highly competitive M25-29 division, Sadar showed commendable effort.

There is potential for improvement in maintaining speed in the latter stages of the race, particularly between miles 8 and 11, where pacing dipped. Keep working on endurance during longer distances to optimize overall race performance.
