Strong Mid-Race Surge and Steady Finish Jason Ju maintained a consistent pace throughout the 2025 Boulderthon Half Marathon, with an average elapsed pace of 11:03 min/mile and a finish time of 2:24:46. His performance showed an interesting strength in the fifth mile, where he recorded a split pace of 6:35 min/mile, improving his placement substantially. However, this surge was followed by a slightly slower fourth mile at 14:42 min/mile, highlighting a variability that may have impacted his overall performance. Despite this, Jason's performance remained quite steady with consistent pacing nearing 11:00 min/mile during the latter part of the race. Notably, his position within the Male 25-29 division varied, starting at 341 and closing at 412. He finished 1795th in his gender category out of 6546 total participants in the event. Focusing on maintaining an even pace could be beneficial for future performances to minimize positioning variations.
