Product Description
A 100-mile trail race demands everything from you and your gear. You’re looking at 24+ hours of focus, and a dead screen at mile 80 isn’t an option.
The Garmin Enduro 4 records for up to 120 hours on GPS alone, or up to 320 hours with solar charging, in a 51mm case that weighs just 66 grams.
Key Features

A Power Sapphire lens, titanium bezel, and 10 ATM water rating handle rain, sweat, and wet crossings. The built-in LED flashlight (white and red) covers early starts. -
Race-day planning
Course Planner sets cut-off times, rest plans, and aid-station strategy for your race. -

Preloaded TopoActive maps with perspective view, plus Up Ahead and NextFork, show what’s coming. 64GB holds your maps and music. -
Hill-smart pacing
Grade-adjusted pace targets account for climbs, so slow uphill miles don’t wreck your plan.
How the Battery Lasts That Long
The long runtimes come from a 1.4-inch memory-in-pixel display, a screen that stays readable in sunlight while sipping power. The Power Sapphire lens doubles as a solar panel. Garmin rates the solar figures at 50,000 lux (bright outdoor sun), and the 90-day figure assumes three hours a day outside at that brightness. Shaded trails and short winter days land closer to the non-solar numbers.
How to Use Garmin Enduro 4
Power mode: Choose Max Accuracy for shorter efforts and Max Battery for the longest recordings.
Solar charging: Keep the lens facing daylight whenever you’re outside.
Multiday efforts: Group consecutive days into a single Garmin Epic in Garmin Connect to see your combined data and share it with family and friends.
Stop settling for a watch that quits before you do.
