Suunto just rolled out a new software update — version 2.44.52 — for the Vertical, Race, and Race S watches. It’s labeled as a hotfix, but don’t let that fool you.
The tweaks inside actually make a real difference if you use your watch daily for workouts, recovery, or sleep tracking.
What’s Inside the Suunto Update 2.44.52?(Hotfix 2025 Q3)
Here’s what Suunto tweaked with this release:
- Cycling data is now sharper. You can adjust your bike sensor’s wheel size manually, which means more accurate distance and speed tracking.
- Sleep tracking got an upgrade. The algorithm is smarter, so your nightly rest reports should look a lot closer to reality.
- Recovery stays in sync. Your watch and the Suunto app now play nicely together — no more mismatched numbers.
- ZoneSense is fixed. The zone indicator bug is gone, so you’ll get proper training feedback again.
- Crash fixes. Several causes of random watch crashes have been squashed, making everything run smoother.
Why This Matters
This update isn’t about adding flashy new features. Instead, it focuses on accuracy and stability — the stuff that really matters when you’re relying on your watch for workouts or recovery tracking.
Cyclists will see better ride data, runners will appreciate reliable zone feedback, and everyone will benefit from fewer glitches.
In short, it’s one of those updates that doesn’t sound exciting on paper but makes the watch feel more dependable in real life.
How to Install Suunto Software Update 2.44.52
Suunto keeps it simple:
- Automatic update: If your watch is paired with the Suunto app, it’ll download in the background and usually install overnight (as long as the battery is at least 50%).
- Manual update: Don’t feel like waiting? Go to Settings → General → Software Update on your watch and run it yourself.
Final Word –Software updates for Suunto watches
Suunto’s 2.44.52 hotfix is a nice little upgrade that fixes nagging issues and makes tracking more accurate—nothing dramatic — just a cleaner, more stable experience.
