Sauce for Zwift™

A collection of add-ons and replacement widgets for Zwift

Sauce for Zwift™ extends the zwift cycling and running simulator with more stats and pretty things.

Requirements:

As of July 2022 Sauce is a full encrypted game client that "watches" your normal Zwift account like a 2nd instance of Zwift itself. As such, you'll need to create a second login (free is fine). Although a bit annoying this does allow you to run S4Z on any device, anywhere.

  • See how much power you're saving by being in the draft.

The gaps are real values from when riders crossed the same point. Geometric based estimates are only used as a fallback when road positions are not yet available (rare).

  • Average and Max for power, HR, cadence, speed and event draft
