Ride any road at home. See the road, feel the climb: ride any route in 3D, from your local loop to the Stelvio, while your smart trainer sets every gradient. Then ride out together: your group can talk, chat and share one live map phone to phone, with no signal, no server and no account. Up to 200 m rider to rider, and further as phones relay it down the line.
