This is a service that matches RUNNET members who have entered a competition but are unable to participate in the event due to work, injury, or other circumstances with another member who wants to enter.

It can meet the needs of both 'people who can no longer participate in the event' and 'people who want to participate from now,' allowing as many people as possible to join the tournament.

After the enrollment deadline, it is also possible to compensate for the number of people lost due to invalid entries (no convenience store payment).
