The Marathon Challenge Cup (MCC), Half Marathon Challenge Cup (HMCC), and MCC100 (Marathon Challenge Cup 100) are projects that support everyone challenging themselves in full marathons, half marathons, and 100km races. They work with popular races held nationwide to widely promote the appeal of these events and provide backup for runners by deepening their enjoyment of running.

We offer various services to support amateur runners, such as the "MCC Annual Award" to recognize runners and event organizers who have made outstanding challenges and efforts, special completion certificates, and the "MCC Grand Slam 1000" to celebrate completing a total of 1000 km across affiliated events.
