Expert opinion

Enduro 3 gives ultra runners Course Planner for cut-off times and aid stations, the ultrarun activity with an automatic rest timer, ClimbPro for the climbs on a course, and NextFork and dynamic round-trip routing on preloaded TopoActive maps. It was the first Enduro with the ECG app and with rucking and pack weight, and it also has Training Readiness, Endurance Score, Hill Score and hands-free voice control. The battery is rated for 120 hours of GPS, or 320 hours with solar, and for 36 days as a smartwatch, or 90 days with solar, in a 63g watch with a built-in flashlight. Enduro 4 replaced it in October 2026 with the same case, display and battery life, and added Garmin Epic and grade-adjusted pace based workouts. Guaranteed security updates for Enduro 3 ran until 27 August 2026.
