For serious runners and outdoor adventurers, the latest software update from Suunto is a game-changer, adding deep biomechanical insights directly to their wrist.
HELSINKI, Finland – Suunto continues to refine the experience for its flagship smartwatch users with a significant new firmware release. The company has begun the phased rollout of software version 2.48.16 for both the robust Suunto Race 2 and the ultra-tough Suunto Vertical 2, which only hit the market in late September 2025.
This update isn't just a routine bug squasher; it's a feature-packed enhancement that dives deep into the world of advanced running metrics, giving athletes unprecedented insight into their form and efficiency.
Deeper Insights: Ground Contact Time and Vertical Oscillation
The headline features of this update are two new, highly-requested running dynamics: Ground Contact Time (GCT) and Vertical Oscillation.
For the uninitiated, these terms might sound complex, but they are crucial for improving running economy and preventing injury.
- Ground Contact Time: This metric measures, in milliseconds, exactly how long your foot spends on the ground with each step. A shorter GCT is generally associated with a more efficient, spring-like running gait, often seen in elite runners.
- Vertical Oscillation: This tracks how much your torso "bounces" up and down with each stride, measured in centimeters. Excessive bounce is wasted energy, and reducing it can lead to a smoother, more efficient, and faster run.
Both of these metrics are now seamlessly integrated into the running log summary within the Suunto ecosystem, allowing users to track their progress over time and correlate it with other data like pace and heart rate. For a complete breakdown of all the technical details, you can always check the official Suunto Race 2 release notes and Suunto Vertical 2 release notes.
As highlighted in a recent report by Gadgets & Wearables, these advanced metrics were a key differentiator for higher-end running pods and watches, and their inclusion in the Race 2 and Vertical 2 solidifies Suunto's position in the competitive training watch market.
Beyond Running: Quality-of-Life Enhancements and Crucial Fixes
While the new running dynamics are the star of the show, Suunto hasn't overlooked the broader user experience. The update includes several thoughtful improvements:
- A Refreshed Morning Report: Suunto mentions it has made improvements to its popular Morning Report feature, which provides a daily summary of recovery, sleep, and weather. The company has been somewhat cryptic about the specific changes, leaving users to discover the new tweaks for themselves.
- Treadmill Calibration Reminder: For indoor runners, a new notification will now helpfully remind you to calibrate your treadmill runs, ensuring your indoor distance and pace data are as accurate as possible.
- "All Apps" Widget: Navigating your watch is now even easier with the addition of an "All apps" option in the widget list, providing quicker access to your entire suite of applications.
- Squashing Battery Drain Bugs: Perhaps most importantly for day-to-day use, Suunto confirms it has tackled two specific problems linked to unexpected battery drain and issues with the button lock function. This should translate to more reliable battery life and a smoother overall interaction with the device.
How to Get the Update
The phased rollout for software version 2.48.16 officially began on November 10th, 2025.
As is standard practice to ensure stability, the update will not reach all Suunto Race 2 and Vertical 2 users simultaneously. The update will be delivered automatically through the Suunto app on your smartphone. To ensure a seamless installation, make sure your watch has at least a 50% charge and is connected to the app overnight.
When the update becomes available for your specific device, you will be able to download and install it directly via the Suunto app. If you're looking to get in on the action, the Suunto Race 2 is currently available for purchase at Amazon for $599.
This substantial update demonstrates Suunto's continued commitment to supporting its devices long after their release, adding significant value and ensuring that users of the Race 2 and Vertical 2 have access to some of the most advanced training tools available on the market today.
