How to Choose the Best Trail Running Watch
GPS Accuracy and Connectivity
For trail running, GPS is the backbone. You need a watch that locks onto satellites quickly and maintains accuracy even under dense tree cover or in canyons. Look for watches with multi-band GPS or at least robust GPS chips. Both our picks offer reliable tracking, but the Garmin Forerunner 55 uses advanced GPS that rivals top-tier models. The moutarlier also boasts fast signal lock, but it’s best used in open outdoor areas.

Battery Life
Trail runs can last hours. You don’t want your watch to die mid-adventure. The Garmin Forerunner 55 offers up to 2 weeks in smartwatch mode and 20 hours in GPS mode, making it a marathon-ready companion. The moutarlier provides a week of heavy use or 20 days of light use, enough for most weekend warriors. Consider how often you’ll be away from charging.
For rugged outdoor excursions, some runners also consider best hunting watches for their long battery life.
Durability and Water Resistance
You’ll be crossing streams, facing rain, and likely bumping into rocks. A rugged build and water resistance are non-negotiable. The moutarlier has a shock-resistant metal body and 50m water resistance, making it ideal for swims and heavy downpours. The Garmin Forerunner 55 is also built for the outdoors, though it’s not as militarily tough. Both handle sweat and splashes easily.
