For endurance athletes, battery life can be as crucial as performance tracking, especially when tackling ultramarathons, multi-day hikes, or remote outdoor adventures. Garmin is taking on that challenge with the Enduro 4, its latest solar-powered GPS smartwatch designed to keep going long after conventional wearables need recharging.
Featuring an energy-efficient 1.4-inch Memory-in-Pixel (MIP) display and solar charging technology, the Enduro 4 delivers up to 320 hours of battery life in activity mode and an impressive 90 days in smartwatch mode, under Garmin’s specified solar charging conditions. Combined with advanced training metrics, improved mapping capabilities and a lightweight construction, the smartwatch is built for athletes who want to push their limits without worrying about running out of power.
Extreme Battery Life for Longer Adventures
At the heart of the Enduro 4 is its emphasis on endurance, with Garmin introducing comprehensive power modes that allow users to balance tracking accuracy against battery consumption.
The Max Accuracy mode prioritises full-featured activity tracking, making it suitable for shorter training sessions and races where detailed performance data matters most. For extended expeditions, Max Battery mode optimises power consumption, allowing the watch to record activities for up to 320 hours with sufficient solar charging.
This flexibility is particularly useful for ultrarunners, backpackers and multi-day hikers who may spend several days away from charging facilities. Rather than constantly monitoring battery levels, users can select the power mode that best suits their adventure.
The solar charging lens further extends battery endurance, making the Enduro 4 a practical companion for long-distance challenges where access to electricity may be limited.
Smarter Training with Grade-Adjusted Metrics
Beyond battery performance, Garmin has introduced several new training features designed to help athletes better understand their effort across challenging terrain.
Grade-adjusted pace-based workout targets take elevation changes into account, helping runners maintain an appropriate effort level when tackling steep climbs or downhill sections. Instead of focusing solely on conventional pace measurements, athletes can train according to the demands of the terrain.
Meanwhile, grade-adjusted rolling pace provides a real-time view of performance over changing gradients, offering a more useful indication of effort during trail runs and mountainous routes.
The Enduro 4 also introduces stamina zones and a stamina curve, allowing users to monitor how their endurance changes throughout an activity. By analysing fitness levels and training history, these features provide additional insight into how much energy an athlete may have available for the remainder of a workout or race.
For endurance athletes who need to manage their effort carefully over long distances, these metrics could prove particularly useful in avoiding an overly aggressive start and maintaining a more consistent pace.
Faster Navigation for the Great Outdoors
Navigation is another area receiving a significant upgrade. With 50 per cent more RAM than the Enduro 3 and an updated mapping engine, the Enduro 4 delivers 30 per cent faster map panning for smoother navigation.
Built-in routable maps allow users to explore unfamiliar routes, while the new Perspective View provides a clearer representation of the terrain ahead. By showing more detail at different distances, the feature helps hikers and trail runners better anticipate upcoming turns and changes in their surroundings.
Whether navigating a remote mountain trail or exploring a new hiking route, the improved interface is designed to make checking directions quicker and more intuitive.
With 64GB of onboard storage, users also have additional space for maps, music and activity data, making it easier to prepare for longer adventures without relying heavily on a smartphone.
Turn Multi-Day Adventures into One Epic Story
One of the more interesting additions is Garmin Epic, a new feature that allows users to combine multiple activities into a single adventure within Garmin Connect.
Rather than viewing each hike, run or cycling session as a separate entry, users can group activities completed over several days, weeks or even months into one cohesive record.
For example, someone completing a multi-day hiking expedition can bring together individual stages, photographs and performance data to create a complete overview of the journey.
The finished Epic can then be shared with family and friends, offering a more engaging way to document memorable outdoor experiences.
It is a thoughtful addition that recognises how endurance activities are often about the overall journey rather than individual workouts.
More Ways to Track Fitness and Performance
With more than 100 activity profiles, the Enduro 4 extends well beyond running and hiking.
Garmin has introduced enhanced indoor rowing tools, including VO2 max estimates and power curve analysis, giving rowers additional insight into their cardiovascular fitness and performance.
Rucking enthusiasts also benefit from expanded tracking capabilities, including the ability to adjust pack weight during an activity and set specific targets such as calories burned.
These additions make the smartwatch suitable for athletes who incorporate different forms of training into their routines, whether building endurance, improving strength or preparing for demanding outdoor events.
Lightweight Design Built for Tough Conditions
Despite its extensive features, the Enduro 4 weighs just 66 grams, making it remarkably lightweight for a 51mm outdoor smartwatch.
Its construction combines a titanium bezel, fibre-reinforced polymer case and scratch-resistant Power Sapphire lens, providing durability without unnecessary bulk.
The smartwatch also features a 10 ATM water resistance rating, making it suitable for demanding outdoor conditions and water-based activities within the device’s specified limits.
An integrated LED flashlight offers adjustable white illumination and a red-light option, providing practical assistance when navigating in low-light environments, setting up camp or searching through equipment after dark.
Garmin has also introduced a new ComfortFit Fabric Band, designed to offer a secure and comfortable fit during extended wear. Its moisture-wicking construction helps manage perspiration, while QuickFit compatibility makes swapping bands more convenient.
Singapore Pricing and Availability
The Garmin Enduro 4 will be available in Singapore from 30 October 2026, with a suggested retail price of S$1,219.
It will be sold through Garmin Brand Stores, the Garmin Online Store, Lazada, Shopee, Takashimaya and selected authorised retailers.
