Today, Hammerhead officially joins Wahoo and Garmin in sending outdoor activities from riders’ Karoo head units to Zwift’s systems. This is good news for Hammerhead users, as those outdoor rides automatically sent to Zwift are included in Fitness Tracking metrics, earn XP, and help keep your Zwift Streak alive! Read on for details…
Connecting Hammerhead to Zwift
For now, the place to connect your Hammerhead account to Zwift is via your account Connections settings page at zwift.com (zwift.com/settings/connections).
Zwift will be rolling out a Companion app update in the next week or so which includes Hammerhead support, so Zwifters will be able to manage the Hammerhead connection through the app beginning August 19. But we figured Hammerhead users would want to know they can hook up their accounts today via the web.
Navigate to your account’s Connections page and click “Connect” under Hammerhead:

You’ll need to log into your Hammerhead account on the next screen, then give Zwift access to read and download activities:


When you’re finished, Hammerhead will show as connected on your account’s Connections page at zwift.com.
Hammerhead Rides in Zwift Companion
Once you’ve connected your Hammerhead account to Zwift, any outdoor rides saved to your Hammerhead account will be sent to your activities list in the Companion app and included in your Fitness Tracking metrics.
I’ve been testing it myself for a couple of weeks now, and everything appears to be working smoothly. Activities imported from Hammerhead include the Hammerhead logo:

Once you connect your Hammerhead account, the past 90 days of activities will be sent to Zwift for processing and integration into your fitness metrics.
