Zwift version 1.93 begins its phased rollout today. This is a significant update, adding a new HUD panel, additional HUD metrics, and fixing an irksome streak bug. Read on for details…
4 New HUD Metrics
This update adds 4 new metrics to the in-game HUD:
- CORE Temperature*
- Heat Strain Index (HSI)*
- Weighted Power (WP)
- Left/Right Power Balance (see note below)
* the CORE Temperature and Heat Strain Index (HSI) metrics require a CORE sensor. Connect your CORE sensor to your HRM using the CORE app, then the CORE sensor will show up as pairable in the Heart Rate box on the pairing screen. (We published a post 2 years ago about using the original CORE sensor for heat training on Zwift, and a lot has changed since then! Watch for an upcoming post about heat training on Zwift using CORE.)
Two additional metrics, Average W/kg and Average Speed, will be added very soon. They were initially included in this week’s release, but a bug was found in final testing.
Setting Up Left/Right Power Balance
For L/R Balance to work in the HUD, you’ll need to pair a device as your “power” source which transmits Left and Right power via Bluetooth (ANT is not currently supported). Here’s what that looks like (here I have Favero Assioma pedals paired as power source, and my Wahoo KICKR paired for resistance and cadence):
New Ride Stats Panel
A new Ride Stats panel has been added on the left, showing your Critical Power across five standard time windows:
- 5 seconds
- 1 minute
- 5 minutes
- 20 minutes
- 60 minutes
“Critical Power” in this context is the maximum average power you achieved across a given time interval.
The panel also includes two additional metric slots, which you can configure under Settings>HUD to show any of the 11 available metrics:
By default, the new Ride Stats panel won’t show while you ride. Click the “Toggle Side Display” button in the action bar to swap between showing segment leaderboards and the Ride Stats panel. (We’d love to see Zwift saving our preference here, so we don’t have to toggle the Ride Stats panel every time we ride.)


As shown above, if you trigger a split during your ride, this will pop in just above the Ride Stats panel.
Route Badge Indicator
A route badge icon has been added to the minimap, making it easy to know whether you’ve earned the route badge for the currently selected route:


The white icon indicates that you have not yet earned the route badge, and the green icon indicates that you have already earned the route badge.
If a route does not have an accompanying badge, this icon will not be shown.
Outdoor Ride Streak Bug Fixed
Zwift started importing outdoor rides from Garmin and Wahoo back in April, but there was an odd bug: if your first ride of the week was an outdoor ride that was imported into Zwift, you wouldn’t get your streak extension XP bonus, even if you rode on Zwift later in the week!
Zwift says this bug is now squashed. You still have to ride on Zwift to earn your streak extension XP bonus – outdoor rides extend your streak, but don’t earn that bonus. As Zwift says, “Your first Zwift indoor ride after an external activity earlier in the week will now show the streak screen and grant the XP bonus.”
Release Notes
Zwift provided notes on additional tweaks and bug fixes in this update:
- For the Americans: Fixed an issue that could cause Climb Portal cards in the Home Screen to only show distance in metric units.
- Fixed an issue that could cause Zwifters to get stuck on the Tour Of Tewit Well route in Yorkshire if riding at low power levels.
- Android: Improved the appearance of workout arches.
- iOS: Fixed a crash that could occur when taking screenshots in rapid succession.
- Mac: Fixed an issue that could cause the background of the top-left HUD section to be transparent.
- Mac, Apple TV: Stability improvements.
