Garmin Enduro 4 Preview 2026: Everything We Know

A new Garmin device bearing regulatory model number A05216 cleared the FCC database on 23 June 2026, pointing strongly to an imminent successor to the Garmin Enduro 3 ultra-endurance GPS watch. Garmin has not officially announced the product, but the filing category and timing leave little doubt about what is coming — and if history is any guide, a launch within the next 60–90 days is likely.

What the Garmin Enduro 3 Already Offers

Before speculating on the Enduro 4, it is worth understanding the baseline the Enduro 3 sets. Launched in October 2024, it remains the benchmark for ultra-endurance triathlon and running watches:

  • Battery life: up to 110 hours in standard GPS mode (all systems); up to 286 hours in Expedition GPS mode
  • Solar charging: the DLC titanium model's solar lens adds meaningful runtime on long outdoor sessions
  • GPS: dual-frequency multi-band GNSS for accuracy under tree cover and in cities
  • Display: 1.4-inch MIP at 280×280 pixels — always-on, excellent in direct sunlight
  • Maps: full topographic maps preloaded; turn-by-turn navigation
  • Training features: HRV Status, Morning Report, Daily Suggested Workouts, Training Readiness, PacePro, ClimbPro
  • Music: offline streaming storage

The Enduro 3 is currently available on Tredz at £699.99 — if you need an ultra-endurance watch now, it remains the right call.

What to Expect from the Garmin Enduro 4

Based on the Enduro 3's specifications and Garmin's recent product trajectory, here is what we would reasonably expect — though the manufacturer has not confirmed any of these details:

  • Battery life: we'd expect an improvement on the Enduro 3's 110-hour figure — possibly 120–130 hours in standard GPS mode, based on Garmin's typical generational battery gains
  • Display: Garmin has historically kept MIP on its endurance watches to protect battery life; AMOLED is possible but we would not assume it until confirmed
  • AI coaching: Garmin rolled out enhanced Daily Suggested Workouts and Training Readiness across its 2025 range; the Enduro 4 will almost certainly carry these as standard
  • Trail enhancements: based on the Enduro 3's mountain-sports focus, we'd expect expanded off-road features — improved grade-adjusted pacing, route recalculation and ski/snowboard modes may be refined
  • Connectivity: Garmin has been integrating deeper Bluetooth sensor ecosystem support; the Enduro 4 likely follows that trajectory
  • Pricing: expect a similar bracket to the Enduro 3 — around £699–£799 at launch — though Garmin has not indicated otherwise

None of the above is confirmed. The FCC filing tells us a device exists and is approaching retail readiness — it does not reveal specs. We will update this page the moment Garmin makes an official announcement.

When Will the Garmin Enduro 4 Launch?

FCC regulatory clearance typically precedes a consumer product launch by approximately 60–90 days. That places the Enduro 4 in the late-summer to early-autumn 2026 window — August to October. Garmin's CEO Cliff Pemble confirmed "significant H2 2026 product launches" in a recent investor briefing, which is consistent with this timeline.
