Consistent Performance with Strategic Pacing Jeho Oh completed the 2025 Boulderthon Marathon with an official time of 4:21:35, maintaining a steady overall pace of 9:59 min/mile across the 26.2-mile course. Notably consistent, his first half averaged around an 8:53 min/mile pace, with his fastest mile at 8:07 achieved around mile 12. Jeho ranked 12th in his M50-54 division, highlighting a solid performance in a competitive field, placing him well in the top half overall. Jeho started strongly, with splits in the first half ranging from 8:41 to 9:00 min/mile. While the second half showed a gradual slowdown, indicative of a slight pacing adjustment, he maintained effort and focus to finish strong. The adjustment between miles 15 and 18, hitting splits of over 10 min/mile, suggests an area to explore for maintaining pacing consistency deeper into the race. Consider implementing strategies like interval training to sustain speed over longer distances.
