Zwift version 1.90 begins its phased rollout today. It includes the much-requested Splits feature, along with some visual tweaks and bug fixes. Read on for details…
New Splits Feature
Zwifters have long requested the ability to trigger laps/splits in game, allowing us to record our own custom interval data while riding in Zwift. Cycling head units have long offered this functionality, so many riders are already familiar with the concept of a “lap button” you can click so the head unit will display data for your current “lap”, including average power, length of time, and speed/distance.
You can trigger a new split in several different ways.
- Click the “New Split” button in the Action Bar (which is also in the Companion app)
- Click the on-screen lap button in the Splits HUD (on all platforms except AppleTV)
- Use the tab key on your keyboard (this will not work in a workout, however, as this is the shortcut for skipping the interval)
- If you own the Zwift Ride you can configure the left drop button to trigger a new split:

The new Splits HUD displays the time, distance, average power, and average heart rate of each split. It also shows a color-coded power zone duration bar that functions just like the bar at the top-left below your power number, except it’s only showing power durations for each specific interval.
Once you’ve triggered a split, you’ll have access to another new “Toggle Side Display” button in the Action Bar next to the New Split button. This swaps the side display between the Splits HUD and the Leaderboard.
Splits data is written to your FIT file, so it can be displayed later on in other platforms like Strava, Garmin, Intervals.icu, etc.
Note: structured workouts will trigger a ”lap” for each interval block, as they always have. To view these splits after your workout, press the Toggle Side Display button in the Action Bar.
Here’s a quick video walkthrough of how it works in game:
There are a few minor UI bugs that Zwift still needs to iron out, including the list of splits not scrolling to the top when you click away from that list, and some typesetting being a bit misaligned, especially in non-English languages.
But the functionality is in place and working well, as far as we can see. Let’s do the splits!
Updated Lighting Effects
If you’ve noticed snazzier lighting effects during your recent Zwift sessions, you’re not hallucinating. Here’s a quick video screenshot recorded in Watopia on version 1.90:
Zwift has been experimenting with improved lighting effects lately, and while they haven’t mentioned it in any of the update notes, more and more Zwifters are starting to notice lighting changes. Our guess is that Zwift is rolling out the updated lighting to specific groups of users on certain types of hardware.
More Release Notes
Zwift provided notes on additional tweaks and bug fixes in this update:
- Improved the appearance of flat routes in the mini-map route profile.
