Garmin Enduro 4 51 mm GPS Sports Watch

Battery life and solar charging

Smartwatch mode lasts up to 36 days without solar and up to 90 days when solar charging conditions are met. During an activity, choose a mode to suit the recording accuracy and battery life you need. Extended mode delivers up to 120 hours, or up to 320 hours with solar.

Readable display and flashlight

The always-on 1.4″ MIP display uses ambient light to stay easy to read in sunlight while saving battery power. Solar Power Sapphire glass protects it against scratches. Touch controls are complemented by buttons. The built-in LED flashlight offers adjustable white light and a red light mode to help you find your way in the dark.

Maps and route guidance

Preloaded TopoActive maps show the surrounding terrain and your route. SatIQ automatically selects a satellite mode for the conditions, balancing position accuracy and power use. ClimbPro shows the climbs remaining on a planned course; NextFork displays the distance to the next junction and the trail name. Add aid stations, checkpoints and cutoff times to your race plan.

Pacing and managing your effort

Grade-adjusted pace helps you compare your effort on hills with running on level ground. New Stamina zones and endurance curves show how your remaining energy changes during an activity. Enter your pack weight for hiking and trail running so the watch can account for the load you carry.

Training and recovery

More than 100 sport profiles are complemented by Garmin Coach plans. Training readiness draws on sleep, recovery and training load, among other factors, helping you decide between a hard session and rest. Garmin Epic brings together activity, health and performance insights throughout a multiday adventure.

Health and smart features

The watch tracks heart rate, heart rate variability, sleep, stress and Body Battery energy. The Garmin ECG app records from your wrist in supported countries for users aged 22 and over; current software is required. Pair a phone to receive notifications. Listen to stored music through Bluetooth headphones without a phone, and use Garmin Pay with a card from a participating bank.

Battery life

All figures are “up to”: without solar / with solar. Smartwatch, low power and expedition figures assume all-day wear with 3 hours per day outside in 50,000 lux conditions. Activity figures assume exposure to 50,000 lux throughout use. “Unlimited” applies only when these conditions are met. Actual battery life depends on settings, sensors and use.
