No, Zwift requires an active internet connection to work, and it cannot be used offline. Zwift is an online virtual cycling platform that streams the virtual world, graphics, and other features to your device in real time, and it requires a stable internet connection to maintain this connection. If you experience a temporary loss of internet connection during a Zwift session, the app will continue running in \\"offline mode,\\" and you'll be able to finish your ride, but you won't be able to interact with other riders, see other riders on the road, or save your ride data to Zwift servers.
