I need some help and I am new to Zwift and really enjoying it. My mileage and speed in Zwift vary to that if my Garmin 920xt?
Also how does Zwift work out your watts if you don’t have a power meter ( I have the Garmin cadence and speed sensor 2). I also cannnot get my Garmin 920xt hr monitor chest strap to sync with Zwift? I use Zwift on my phone.
Thank you for your help. Also how are people able to text messages to other riders while riding and how are they doing it as I don’t see a space.
Zwift and your Garmin bike computer will never match up, the Garmin doesn’t know what is happening in the virtual world like hills, powerups, drafting, etc. It only knows the speed of your rear wheel and converts that to distance as if on a flat road.
If you dont have a power meter or smart trainer then Zwift estimates your power based on the trainer you are using. They have power curves for a selected number of supported trainers, hopefully you have one that is supported.
Most people probably use the companion app to message people, but if you are using your phone to run Zwift then this isn’t an option for you (unless you have a 2nd phone or old one lying around). You should be able to swipe up from the bottom of your screen to get access to camera angles and other items where you will find a messaging icon.
Zwift takes the wheel speed broadcast by your speed sensor and the power curve of the trainer you select on the Pairing Screen and converts that to virtual watts. With those watts, the weight entered, height entered, in-game bike used, in-game drafting (Tri and TT bikes get no drafting boost), in-game wheel set, in-game road surface, and in-game virtual elevation changes your in-game speed is determined.
