Consistent Start with a Need for a Stronger Finish Kwangyeong Jeong delivered a consistent performance at the 2025 Boulderthon, maintaining a steady average pace of 8:55 minutes per mile in his marathon debut. Early on, Kwangyeong displayed impressive consistency, with the first five miles averaging around 8:00 minutes per mile and achieving notable placement in his age division, peaking at 26th in mile 5. His pacing between miles 1 and 14 remained within a narrow range, indicating strong early race management. In the latter stages of the race, a notable slowdown occurred, with the pace widening to the 9:00-10:45 minute per mile range from mile 20 onwards. Split times above 9:00 minutes per mile from mile 18 indicate a need for stamina development to maintain the earlier pace consistently. Despite the challenging finish, Kwangyeong's consistent early race execution is commendable. Focusing on endurance in future training could help in achieving a stronger finish and maintaining placement within his division.
