Garmin Enduro 3 Deal Challenges Enduro 4 and Fenix 9 Pro

The Garmin Enduro 4 has launched at $899, but the Enduro 3 is currently $789 on Amazon, according to Tom’s Guide. That $110 gap matters because this is a very small hardware refresh, while several of the Enduro 4’s new software features are expected to reach the older watch. For endurance athletes who want Garmin’s deep training and navigation toolkit without paying flagship money, the Enduro 3 is suddenly the more compelling buy.

This is also a useful reminder that Garmin’s range is splitting into very different value propositions. At the lighter, solar-equipped Enduro end, the outgoing model looks strong against the new one. At the AMOLED running-watch end, Tom’s Guide finds the $449/£389 Coros Pace 4 Pro offers a more complete adventure package than the $549.99/£459.99 Garmin Forerunner 570 for many athletes. Garmin still has real strengths. We just need to be clear about which ones we are paying for.

Enduro 3: choose the old watch while it is discounted

The Enduro 4 brings a silver bezel, Garmin’s newer ComfortFit band, 64GB of storage rather than 32GB, plus a faster processor and more RAM intended to make map panning and zooming quicker. It also gets a perspective map view and an archery feature that will not come to the Enduro 3. The ComfortFit band is sold separately, though, so it is not a reason by itself to replace the older watch.

The more consequential additions, including Garmin Epic for grouping activity data across a multi-day event and the newer stamina feature introduced with the Fenix 9 Pro, are due to arrive on the Enduro 3 through software updates. That makes the older Enduro a particularly sensible ultrarunning or bikepacking option: its core sports tracking, training analysis and navigation are already close to Garmin’s premium offering. Tom’s Guide says the Enduro 3’s MIP display with solar charging also delivers longer battery life and a lighter design than the 51mm Fenix 9 Pro.

Forerunner 570: Garmin’s strengths, Coros’s better route tool

The Forerunner 570 and Pace 4 Pro both cover track running, triathlon and open-water swimming, and Tom’s Guide found both excellent for GPS accuracy when using their most accurate multi-band modes. The Garmin earned an edge for wrist heart-rate performance in its testing, with fewer apparent spikes and less lag against a chest strap during intervals. That distinction is worth making: a chest strap reads the heart’s electrical impulses, while the watches use optical PPG sensors that estimate heart rate from blood-volume changes via light.

Garmin’s case is Training Readiness, richer training presentation, NFC payments, streaming music support, Connect IQ apps and the choice of 42mm or 47mm cases. The Coros counters with a 1.47-inch screen, titanium bezel, sapphire crystal, 32GB storage and full offline maps. It is also rated for 21 days of watch use and 30 hours of multi-band GPS, against up to 11 days and 14 hours for the 47mm Garmin. In Tom’s Guide’s always-on, daily-GPS use, the Coros lasted seven days versus three to four for the Garmin.

What disappoints is straightforward. The Forerunner 570 has only breadcrumb navigation, no offline maps and no built-in flashlight, despite its price. The Enduro 3, meanwhile, loses faster map handling, 64GB storage and the Enduro 4’s perspective map view, and buying old hardware may mean its software support ends sooner. Those are real trade-offs, not footnotes.

Our verdict: buy the Enduro 3 at $789 if you want long-running Garmin navigation and training tools, rather than paying $899 for a largely iterative Enduro 4. For runners who prioritize offline maps, screen size and battery life in a lighter package, the Coros Pace 4 Pro makes more sense than the Forerunner 570. Pick Garmin’s midrange watch only if its smarter daily features, smaller fit option and training interface are the priority.
