[Firmware ChangeLog]: What's New in 26.09 | Enduro 2 | GameraSnap

Overview

Garmin has started rolling out stable Software Version 26.09 for the Enduro 2 on April 21, 2026. The official Garmin forum post says the release is currently at 20% rollout, so availability will increase in stages.

That matters for Enduro 2 owners because this watch is built for long sessions, long trips, and long battery life. On a device like this, even relatively small software bugs can become more annoying because they show up in extended real-world use. Version 26.09 focuses on exactly the kind of reliability fixes endurance users should care about.

Official Change Log

Garmin lists the following changes for version 26.09:

Added support for Rally 110/210
Fixed a bug that could stop custom GPS settings from saving in some activity profiles
Corrected a missing translation in the Solar Intensity widget
Fixed cases where the compass calibration tutorial video failed to appear
Resolved invalid Daily Suggested Workout target-type data

Why This Update Matters

Endurance users benefit from better setup consistency

The fix for custom GPS settings not saving is especially relevant on the Enduro 2, where users often tune profiles carefully for battery strategy, navigation, and long-event tracking. Better Stages Power Meter pairing and new Rally 110/210 support also make the watch more dependable in multi-sensor setups.

Stability fixes are important on long outings

Garmin says 26.09 fixes shutdowns in Garmin Coach and while skipping music. Even if those bugs do not affect every user, unexpected shutdowns are exactly the kind of issue endurance-watch owners want removed before a long run, long ride, or multi-day trip.

The smaller fixes improve everyday usability

The Training Effect text fix in German, the Solar Intensity translation fix, the Power Manager text cleanup, and the tutorial-video correction all make the watch feel more refined in normal use, not just during workouts.

How to Install Version 26.09

Charge the watch before starting the update.
Open Menu > System > Software Update > Check For Updates on the watch.
You can also update through Garmin Connect Mobile or Garmin Express.
If 26.09 is not available yet, Garmin may not have reached your device in the phased rollout.

Should Enduro 2 Owners Update?

For most users, yes. 26.09 is a stable release with meaningful reliability fixes. If you are leaving for an event or expedition immediately and cannot test the watch afterward, waiting a little can be reasonable. Otherwise, the changelog makes this look like a sensible update to take.

Conclusion

Software Version 26.09 looks like the right kind of update for the Enduro 2: practical, stability-focused, and relevant to real training use. Garmin is improving sensor support, preserving custom GPS behavior, and fixing shutdown bugs that matter more than cosmetic tweaks on an endurance watch.

Once Garmin pushes it to your device, this stable release is worth installing.
