All-around entertainer Jung Joon-ha successfully completed a half marathon through the Infinite Challenge Run.

Jung participated in the "2026 Infinite Challenge Run in Gyeongju" (hereafter "MuDo Run"), planned and directed by MOst267 (MBC Original Studio), held at the Gyeongju Citizens Stadium in Gyeongbuk Province on the 19th. Following the "MuDo Run" held in Seoul last June, he took on the marathon challenge alongside fans of "Infinite Challenge" in Gyeongju this time.

The Gyeongju "MuDo Run" was held as a unique team-based competition utilizing the chase concept, which was a popular segment of "Infinite Challenge," dividing participants into a "guard team" and a "bandit team." Jung played an active role on the "bandit team."

Known to weigh over 100kg, long-distance running was no easy challenge for the large-built Jung. However, he poured sweat into his running practice, sharing his preparation process for the "MuDo Run" on his social media and earning enthusiastic support. Having previously completed the 10km course at the Yeouido, Busan, and Sangam "MuDo Run" events, Jung reaped the fruits of his hard work by completing the half marathon at the Gyeongju "MuDo Run," sharing various commemorative photos and celebrating his joy with fellow participants.

Meanwhile, Jung has been active across both variety and cultural programs recently, including his YouTube channels "Jung Jun Haha" and "Hawasu." In particular, by combining his unrivaled character with current content trends, he is entering another golden age of his career.

Moving beyond his legendary character from "Infinite Challenge" and proving his unique presence as a versatile content character across all platforms, Jung plans to continue communicating with the public through various media and maintain his prime-time level of activity.
