Yes! RunBet supports Garmin GPS devices, so if you have one you will just need to make sure your runs are being saved in the Garmin Connect app. You can sync the Garmin Connect app with RunBet the same way you would sync Runkeeper or Strava.
You can use other wearable devices as well so long as they can connect to your Runkeeper or Strava accounts (which you can get for free). Refer to Runkeeper for supported wearables here, and refer to Strava for supported wearables here. Note that we can only credit runs that are officially reported through Runkeeper, Strava, or Garmin Connect. This is why it is important to make sure your wearable device is supported and that all your runs appear in one of the supported apps.
