CS Running Team Chasing Speed and Distance in Seoul

Born From a Challenge, Built on a Motto

The name says everything you need to know. "No One Can Stop Us. We Won't Stop." It is not a slogan borrowed from a poster or a brand collaboration. It is a statement of intent, earned through early mornings, hard intervals, and the particular kind of commitment that grows when a group of people decides, together, that they are not finished yet. CS Running Team came into existence in Seoul in March 2020, a moment when much of the world was pressing pause. This crew did the opposite. It laced up and got to work. The origin of CS Running Team runs directly through a programme called Challenge The Impossible, a special training initiative run by Running with Kyunghee, designed to take everyday people and bring them across a full marathon finish line. The programme does not just train the body. It recalibrates the mind. Participants who walk into it often arrive uncertain of what they can do. Those who come out the other side have done something they once considered impossible. For many, crossing that marathon finish line does not signal an ending. It signals a beginning.

From Programme Graduates to a Crew of Their Own

Yedaeun, a former participant in Challenge The Impossible, understood that feeling well. After completing the programme, she did not want to stop training. More specifically, she did not want to stop training alongside people who shared the same drive. So she gathered around ten fellow runners and organised the first session. The goal was direct: break the 5K record. Not as a team average, but as an individual achievement, supported by a collective energy. That first session set the tone for everything that followed. What Yedaeun built is a crew with a clear sense of its own identity. CS Running Team does not try to be everything to everyone. It is focused, purposeful, and honest about what it values. Speed matters here. Distance matters here. Personal bests matter here. This is not a passive environment where running is simply an excuse to socialise, although friendships have formed, inevitably and genuinely. The foundation is performance, and that clarity is what draws the kind of runner who belongs here.

Personal Achievement Without the Pressure

There is a common tension in performance-focused running groups. The drive to improve can easily tip into an atmosphere that feels intimidating, where slower runners feel out of place and newer members feel like they are always playing catch-up. CS Running Team has navigated that tension carefully. Members come from different running levels. Some have been running for years; others are still finding their stride. What holds them together is not matching pace, but matching intent. The crew operates on the principle that challenge and encouragement are not opposites. You can push someone hard and still support them fully. You can demand more of yourself without making others feel inadequate. In practice, this means that a Thursday evening run includes runners at different speeds, on different journeys, all sharing the same road and the same collective refusal to settle. Members learn from each other constantly. A more experienced runner's approach to pacing becomes a lesson for someone newer. A newer runner's hunger to improve reminds a veteran why they started.

Thursday Evenings on the Streets of Seoul

The crew's anchor run takes place every Thursday at 7pm. Seoul is a city that rewards evening runners. By that hour, the light has shifted, the heat of the day has softened, and the city's energy takes on a different character. Han River paths, the slopes around Namsan, the wide avenues of Mapo or Gangnam, Seoul offers a remarkable variety of urban running terrain, and CS Running Team moves through it with purpose. The Thursday session is where the week's intentions become real: where goals discussed in messages become kilometres logged on the road. Beyond Thursday, the crew runs quick sessions on other days of the week. These are not long social runs designed for easy conversation. They are focused, fast, and efficient. They serve the crew's broader training philosophy: consistent, high-quality effort across multiple sessions, building the kind of fitness that shows up on race day. For members who want to improve meaningfully, the additional sessions are where that improvement is forged.

A Small Crew With a Long View

CS Running Team is a small group, around ten members in total. That size is not an accident or a limitation. It is a feature. Small crews move differently from large ones. Communication is direct. Accountability is real. When there are ten people depending on a session, the calculus around skipping it changes. When a member hits a new personal best, everyone knows about it. The shared history builds quickly in a group this size, and the investment each person feels in every other member's progress is genuine. The crew's connection to its roots in Challenge The Impossible also gives it a longer view than some performance crews hold. Running with Kyunghee created that programme to prove something: that ordinary people can finish a full marathon if they train with the right guidance and the right belief. CS Running Team carries that ethos forward. Every member has, at some point, confronted a distance or a pace that felt unreachable. Every member has pushed through it. That shared experience of having once doubted and then exceeded creates a bond that statistics and finish times alone cannot capture.

How to Run With CS Running Team

Runners interested in joining CS Running Team are welcome to reach out through the crew's Instagram, c.s_running, and contact Mingkey directly for details on how to join a session. Thursday evenings at 7pm are the main entry point, and additional sessions throughout the week are available for those who want to commit more fully to the crew's training rhythm. There is no requirement to arrive at a specific pace. The requirement is simpler and harder at the same time: arrive ready to push. Seoul has a growing and vibrant running scene, with crews and clubs spread across its many neighbourhoods and districts. CS Running Team occupies a specific place within that scene. It is the crew for runners who have already caught the bug, who have already tasted what it feels like to cross a line they once thought was out of reach, and who want more. The motto says it plainly. No one can stop them, and they will not stop themselves. In a city that runs hard and fast, that is a promise worth keeping.
