*Importing from Strava is the easiest method to import your workouts but if you don't have or want a Strava account, downloading from your device is another option.

Windows and Mac:  

The Hammerhead Karoo and Karoo 2 are standalone GPS units that are configured by a companion website through the Hammerhead dashboard portal. There is not a direct file sync service to this device, as you must use the Hammerhead website or extension to transfer routes to this device.

You can sync your Routes to Karoo using their custom website based route importer: https://dashboard.hammerhead.io/auth/signup

You can also use the Hammerhead Chrome Extension for easier access.
