Overview
Garmin has started the 20% rollout of Public Beta 31.21 for the Edge 540, Edge 840, and Edge 1040 cycling computers. This beta is much smaller than 31.20, but it still fixes issues that can affect everyday training workflows.
The two official fixes are about Daily Suggested Workouts and Stamina Distance/Duration. Those are both training-facing features, so even a short changelog can matter if you rely on the Edge for structured rides or long efforts.

Garmin Edge 540/840/1040 Beta 31.21 Changelog
Garmin lists two fixes in version 31.21:
- Fixed Daily Suggested Workouts showing on the main menu when toggled off
- Fixed Stamina Distance/Duration
There are no headline feature additions in this release. The value is in making existing training tools behave more predictably.
Why Version 31.21 Is Important
Daily Suggested Workouts should stay hidden when disabled
If you turn off Daily Suggested Workouts, you expect the Edge main menu to respect that choice. This fix should reduce clutter for riders who do not want Garmin's suggested workout flow visible during normal use.
For people who prefer their own training plan, coaching platform, or manual ride setup, this is a small but useful cleanup.
Stamina is only useful when its numbers are consistent
The Stamina feature is designed to help riders understand remaining effort. On Edge 540, 840, and 1040 devices, Stamina can be useful during longer rides, intervals, climbs, and endurance pacing.
That depends on the underlying distance and duration values being correct. Garmin's 31.21 fix should improve confidence in those Stamina screens.
Recent 31.xx Beta Context
This update follows several active beta branch changes:
- 31.20 fixed crash paths, Connect IQ UI lag/freezing, course list stability, elevation profile scaling, weather widget values, and overlay menu behavior
- 31.18 fixed a date-string translation issue
- 31.15 added gear tracking improvements and fixed issues around radar color mode, flat-road climb credit, auto zoom, Strava widget freezing, ClimbPro display, shifter summaries, course navigation crashes, and recent finds search
Version 31.21 is not a big release on its own, but it continues the same cleanup pattern.
How to Install Edge 31.21 Beta
Garmin says beta users need:
- Enrollment in the Public Beta Program
- A configured Wi-Fi network on the Edge
- To open Main Menu > System > About > Check For Updates
After the download completes, you may need to scroll and select Software Update 31.21 manually.
If your Edge shows "Collecting diagnostics...", Garmin asks users to open:
- Menu > System > Diagnostics > Upload RAM Dump
Should Beta Users Update?
Yes, if you are already on the 31.xx beta branch. Version 31.21 is targeted and low-drama: it fixes two visible training-related issues without changing the broader platform.
If you are not enrolled in Garmin's beta program, this is still useful to track because these fixes often indicate what Garmin is preparing for a future stable release.
Conclusion
Garmin Edge 540/840/1040 software version 31.21 Beta is a focused training-workflow update. It makes Daily Suggested Workouts behave more cleanly when disabled and corrects Stamina Distance/Duration behavior.
For riders testing the 31.xx branch, this looks like a practical update to install and verify before the next ride.
