Hi! I understand that your ASICS Runkeeper app tracks your run but doesn’t show any mileage at the end of the activity. Let’s work through this together to find out why that might be happening.

A few quick questions before we start:
- Are you using Runkeeper on your phone’s WebKit browser or the actual app installed on Windows 10?
- During your run, do you see a map or any distance updates as you’re running, or does it only show time?
- Have you recently checked if location permissions for Runkeeper are fully enabled on your device?

While you get back to me, here are some common steps that usually fix mileage not showing in Runkeeper:

1. Check Location Permissions
Make sure Runkeeper has permission to access your location at all times (not just while using the app). On Windows, check location settings and ensure browser or app access is allowed.

2. Disable Battery or Power Saving Modes
Sometimes, power-saving settings interfere with GPS data collection. Double-check your battery settings and disable any that might limit background GPS access.

3. Reset Network and Location Services
- Go to Windows Settings > Privacy > Location. Turn off location, wait a moment, then turn it back on.
- Similarly, restart your internet connection or Wi-Fi to refresh connection to GPS services.

4. Restart Your Device
A simple reboot can clear temporary glitches affecting GPS or data syncing.

5. Check for App or Browser Updates
Since you’re using WebKit on Windows, ensure your browser is up-to-date for best compatibility with Runkeeper’s web app. If possible, try running the activity on the native Runkeeper app (if available) on a smartphone for comparison.

If none of these steps help, it might be due to GPS not properly logging location points, which can happen if there is GPS signal loss during your run or if the app fails to record the data. Also, let me know if you see any error messages or unusual behavior during or after tracking.

Once you confirm some details and have tried these steps, I can guide you further! How does that sound?
