Hyunjin placed 916th out of 2428 participants, ranking 467th in the male category and finishing 70th in the M35-39 division. His placement improved noticeably from early to mid-race, especially between the second and third mile, reducing his place from 1020 to 873 overall. For future races, focusing on maintaining mid-race pace improvements to later miles could further enhance performance. Great job representing K-NREL in Boulder!
