Overview
- Garmin announced the Enduro 4 on Tuesday and lists a suggested retail price of $899.99 with a broader global on‑sale date set for October 9, 2026.
- The company claims the watch can run up to 320 hours in activity mode or up to 90 days in smartwatch mode by combining a 1.4‑inch MIP screen, a Power Sapphire solar lens and new power modes such as Max Accuracy and Max Battery.
- Those battery figures depend on specific sunlight conditions and selected power modes, so real‑world runtimes will vary and require independent testing to verify Garmin’s best‑case estimates.
- Hardware and navigation upgrades include 50% more RAM than the Enduro 3, 64 GB storage, a faster map engine, a 51mm titanium‑bezel case with an LED flashlight and 10 ATM water resistance, while the MIP display trades AMOLED brightness for energy efficiency.
- Garmin added endurance‑focused training tools such as grade‑adjusted pace targets, grade‑adjusted rolling pace, stamina zones and Garmin Epic multiday logging, positioning the Enduro 4 as a battery‑first alternative to the Fenix line for ultrarunners and multiday outdoor athletes.
