TMF VIRTUAL RUN is an entry and ranking platform operated by the Tokyo Marathon Foundation for virtual running events. It enables participants to take part in events using a GPS-connected running app, completing their runs wherever they are and recording their activity through the app. The participation process includes downloading a compatible app, entering an event, linking the app with the ranking website, confirming the connection, and saving a run or other activity. Rankings are announced after participants submit their recorded activity.

The platform provides information to help runners get started, including event details, results, frequently asked questions, and guidance on connecting an app. It also offers a dedicated login for groups. Listed events include the Tokyo Metro Virtual Marathon, which invites participants to run a distance corresponding to the Hibiya Line’s route. TMF VIRTUAL RUN supports virtual event entry and participation while bringing runners together through shared challenges and rankings. The site also provides participation and entry terms, a privacy policy, and contact information.
