My Year in Review: 2023

In 2023, I found myself becoming more involved in running, as reflected in my blog posts this year. This post serves as my annual reflection on the events of 2023. I hope we can extract some lessons from these experiences.

2023 : Year of Running


As the new year started, we got busy planning and setting goals for 2023. Alongside our work, I made time for running. On January 1st, I ran 23 kilometers to celebrate the beginning of the year. Also, I started training for a marathon and accomplished something big: I ran over 30 kilometers for the first time ever. These achievements gave me a boost of energy and determination for the year ahead, both in my personal life and in leading Suitmedia.


It was a month filled with new challenges and exciting experiences. I continued to push my limits in running, achieving a significant milestone by conquering a route with over 1000 meters of elevation gain for the first time. The next day, I participated in the Run Against Cancer (RAC) 2023 event in Semarang, completing a 10-kilometer run to contribute to this meaningful cause. As part of my marathon training journey, I reached a peak distance of 38 kilometers, pushing through both physical and mental barriers in preparation for my debut marathon.


It was an unforgettable month filled with significant milestones and exciting adventures. I achieved a significant milestone by completing my debut marathon at the Tokyo Marathon 2023, a journey filled with determination and triumph. Following this exhilarating experience, I embarked on a nostalgic journey to South Korea after several years, exploring the vibrant cities of Busan, Daegu, and Seoul. The highlight of my time in South Korea was reuniting with my KAIST classmates to celebrate a decade of friendship, reminiscing about old times and creating new memories together. In Seoul, I also had the opportunity to participate in the half marathon event (R2) of the Seoul Marathon 2023, adding another memorable race to my repertoire.  To cap off the month in style, I traveled back to Japan to meet my girlfriend, immersing ourselves in the enchanting landscapes and rich heritage of Osaka, Kyoto, Nara, and Tokyo.
