Below you’ll find a complete step-by-step guide on how to properly sync your app (ASICS Runkeeper™) with the RUN as ONE – GLOBAL Virtual Run Series 2025/2026 challenge. By doing this, your result will be included in the official ranking and you’ll have a chance to enter the Tokyo Marathon 2027 drawing.
App Synchronization Steps
1. Go to the TMF Virtual Run website
• Open the website tmf-virtualrun.jp.
• Click the menu icon (three horizontal lines in the top right corner).
2. Select “App Sync Status”
• In the menu, select the “App Sync Status” button.
3. Choose your event

5. Start the synchronization process
• If your status is “Not synced,” click “Sync App to the Event” or “Sync App”.
6. Log in to ASICS Runkeeper™
• If you have a OneASICS™ account, make sure to log out before syncing to avoid connecting the wrong account (the system may automatically sync your OneASICS™ account even if you don’t want it to).
• Log in to the ASICS Runkeeper™ account you plan to use during the run.
7. Synchronization confirmation
• After successful synchronization, you’ll see the message “Sync Complete” along with your app ID or username—make sure it’s the correct account.
