Garmin has quietly pushed a significant software update to several of its older Forerunner models, bringing stability improvements and crucial bug fixes to some of the brand's most popular running watches.
In a move that will delight fitness enthusiasts who rely on older devices, the navigation and wearables giant has released Software Version 29.05 as a stable over-the-air (OTA) update. The rollout comes just months after the company's June release of Software Version 28.05 and follows a period of beta testing that has now culminated in a polished, production-ready firmware.
Which Garmin Forerunner Models Are Getting the Update?
The latest stable firmware is rolling out to a comprehensive lineup of Garmin's mid-range and premium running watches. Owners of the following devices should keep an eye on their notifications:
- Garmin Forerunner 165
- Garmin Forerunner 255
- Garmin Forerunner 265
- Garmin Forerunner 955
- Garmin Forerunner 965
This broad compatibility means that even runners who haven't upgraded to the newest flagship models will still benefit from Garmin's ongoing software support—a welcome approach in an industry where older devices are often quickly abandoned.
What's Actually Fixed in Version 29.05?
While the changelog might appear modest at first glance, the fixes address several pain points that users have been reporting for months. According to Garmin's official release notes, the update delivers three key improvements:
1. Syncing Strength Personal Records to Garmin Connect Resolved
One of the most frustrating issues for athletes tracking their progress has now been addressed. Previously, many users found that their strength training personal records weren't properly syncing to the Garmin Connect ecosystem. This meant that hard-earned gains in the gym weren't being reflected in their training history or performance analytics. With Version 29.05, that sync interruption has been permanently resolved.
2. Heart Rate and Power Field Configuration Fixed
The update also tackles a separate bug that caused problems when configuring heart rate and power fields from Garmin Connect Mobile. For serious runners and cyclists, heart rate data and power metrics are non-negotiable—they form the backbone of training zones, effort tracking, and performance analysis. The previous configuration glitch made customizing watch faces and data screens unnecessarily complicated, but this latest stable release smooths out the experience.
3. General Bug Fixes and System Improvements
As with most firmware updates, Garmin has also included a sweeping set of general bug fixes and under-the-hood improvements. While the company hasn't elaborated on these specific fixes, users should expect better stability, smoother transitions between apps, and potentially improved battery performance.
What About the Newer Forerunner Models?
For those tracking Garmin's entire ecosystem, the company has already published a stable update for the even newer Forerunner 70 and Forerunner 170 models. This signals that Garmin is taking a comprehensive approach to software maintenance, ensuring that both legacy and current devices receive the attention they deserve.
How to Get the Update
Garmin typically distributes system updates as over-the-air downloads, meaning your watch should automatically prompt you to install the new firmware when it becomes available. For users who prefer a more proactive approach, you can manually check for updates through the Garmin Connect Mobile app or by connecting your device to a computer with Garmin Express.
Why This Update Matters for Garmin Users
For the running community, firmware updates aren't just about new features—they're about reliability. When you're in the middle of a marathon training block or tracking progress toward a personal record, you need your watch to perform flawlessly. The sync issue with strength records, in particular, was a significant headache for multisport athletes and gym-goers alike. By addressing these specific pain points, Garmin is demonstrating that they're listening to user feedback and prioritizing what matters most: accurate, reliable data.
The Forerunner 255, currently available as a refurbished model for $259 on Amazon, has been a fan favorite since its release. It offers a fantastic balance of features and price, making it an excellent entry point for runners who want serious training metrics without breaking the bank.

A Word from the Community
For users looking to read more detailed technical information or share their experiences with the new update, Garmin has an active community forum where discussions are already underway. You can find the official thread and detailed release notes here: Forerunner 255 Series - 29.05 - 100.
Early reports from the forum suggest that the update is installing smoothly across all supported devices, though users are encouraged to ensure their watches have sufficient battery life before beginning the installation process.
The Bigger Picture: Garmin's Commitment to Longevity
In an era where smartwatches are often replaced every couple of years, Garmin's continued support for older devices stands out. The Forerunner 255, for example, was released in mid-2022, and yet it's receiving the same software attention as much newer models. This commitment to longevity not only adds value for existing customers but also makes Garmin devices a smarter investment for those considering a purchase.
The update also hints at what might be coming next. With the foundation of Version 29.05 laid, we could see more feature-rich updates in the future as Garmin continues to refine its platform. For now, users can enjoy a more stable experience and the confidence that their training data is being tracked and synced correctly.
Final Thoughts
Whether you're a competitive triathlete, a weekend warrior, or someone just starting their fitness journey, the Garmin Forerunner series offers some of the most comprehensive training tools on the market. With the release of Software Version 29.05, Garmin is ensuring that older models continue to deliver the performance and reliability their users expect.
