The Core Original Running Man Lineup
The core original lineup of Running Man, which aired its first episode on July 11, 2010, consisted of six fixed members anchoring the show in its formative years. This group established the format of missions, betrayals, and city tours that defined the early seasons. Understanding these six individuals provides the essential baseline for tracking how the show evolved before later cast changes and international adaptations took hold.
- Yoo Jae-suk
- Ji Suk-jin
- Kim Jong-kook
- Lee Kwang-soo
- Gary (Leessang)
- HaHa (Haha)
These members remained the consistent faces of Running Man from its July 2010 debut through key segments of 2016, setting the tone for the program’s blend of athletic challenges, city exploration, and interpersonal dynamics.
Member Roles and Early Format Contributions
Each original member brought a distinct role that shaped how audiences engaged with the show. Yoo Jae-suk served as the central MC and the de facto leader, guiding interactions and often mediating between members. Ji Suk-jin was characterized by his comedic betrayals and fierce competitiveness, frequently emerging as a rival to the main PD-driven narrative. Kim Jong-kook represented the physically dominant member, capable of intense chase sequences and direct confrontations. Lee Kwang-soo provided a balance of loyalty and opportunism, while Gary and HaHa contributed musical perspectives and grounded, relatable humor. Together, these roles formed the operational structure of early missions.
Gary (Leessang) and the Hip-Hop Influence
Gary, member of the hip-hop duo Leessang, joined the show early and quickly became a strategic, cerebral player known for forming temporary alliances and executing complex betrayals. His calm demeanor and sharp tactical thinking helped establish the mental gameplay aspect of Running Man. HaHa, meanwhile, excelled at comedic timing and physical agility, often diffusing tension with lighthearted quips and surprising chase performances. Their combined presence helped diversify the show’s tone beyond pure competition into entertainment-driven storytelling.
Evolution of the Original Lineup and Departures
Over time, scheduling conflicts and new strategic directions led to gradual changes in the fixed cast. Members departed for various reasons, including personal careers and extended international projects, which allowed new personalities to join and shift the group dynamic. This evolution illustrates how Running Man adapted to maintain relevance while transitioning between eras. Tracking these departures helps contextualize the show’s changing strategies and audience reception across different periods.
