How Saved Routes and Courses Work on a Smartwatch

What a saved route or course is

A saved route is a predefined path made of GPS waypoints. It might be a trail loop you downloaded from a hiking service, a running course you drew on a map, or a cycling route a friend shared. The route tells your watch where the path goes, and the watch uses GPS to place you on that path. GPS is a positioning, navigation, and timing service, which is what makes following a route possible: the watch compares your location with the waypoints and tells you what to do next.

Three terms come up: route, track, and course. A route is the planned path you intend to follow. A track is usually the path you actually recorded as you moved. A course is often the same idea as a route, but the word is common in cycling and racing, where it may include start and finish points or segments. For smartwatch purposes these words are often used interchangeably. What matters is that the waypoints are stored on the watch and the watch can guide you along them.

Routes travel in standard file formats, most commonly GPX. In everyday use you rarely open the file itself. You import it into an app connected to your watch, and that app syncs the waypoints to the watch. The watch does not need to parse the file; it needs the waypoint list and a screen that draws the course.

How routes get onto your watch

The phone app is the usual bridge. You plan or import a route on your phone in the watch's companion app or a third-party service, and the app pushes the route to the watch over Bluetooth. On Wear OS watches, Google Maps can provide turn-by-turn directions on the wrist. The Apple Watch User Guide describes a Compass app where you can view and add waypoints and use Backtrack to retrace your steps, which are built into the watch rather than imported as files.

Third-party services also move routes to your watch. The Wear OS platform lists Strava and AllTrails as apps you can use to track exercise and explore. When you save a route in one of those services, the same account can usually pull it onto your watch. Not every watch works with every service, so before you buy, check that the apps you plan to use support the watch platform you are choosing.

The import process usually happens through the phone, but some watches let you receive a route directly through the companion app when the phone is nearby. The watch stores the route locally, so once the transfer is done you do not need the phone to follow it.

What the watch shows while you follow

The guidance you see depends on the app and the watch. Turn-by-turn navigation shows an arrow and a distance to the next turn, which is how Google Maps behaves on Wear OS. A breadcrumb trail is a line on a small map that shows the path you have taken and the path ahead. Breadcrumb navigation is common on outdoor watches and works without street names or addresses.

Apple Watch Compass lets you add waypoints and use Backtrack to retrace your steps if you get turned around. Many watches also show distance remaining, elevation gain, and an off-course alert when you drift from the route. These cues help on trails and in open country where there are no roads.

Offline maps make these cues useful without a signal. On Wear OS, when you download a map to your phone, you can access it on the watch even if the phone is left behind. Apple Watch also offers offline maps in the Maps app. Learn how offline maps work.

Which apps and services you need

Most route following needs three pieces: a companion app on your phone, a mapping or fitness service with route files, and the watch software. The companion app pairs the watch and manages the connection. The mapping service, such as Strava or AllTrails on Wear OS, is where you find or create routes. The watch software draws the course and runs the screen.

You do not always need a separate app if the watch platform includes navigation. Apple Watch has built-in Compass waypoints and Backtrack, which cover the basics of following a route you create as you go. For a planned GPX route, you will likely want a service that can import the file and sync it to the watch. Route import and courses explains the difference between route import and breadcrumb navigation in more detail.

For dedicated outdoor watches, Garmin's approach often includes the ability to sync courses from the Garmin Explore or Connect app, while Apple Watch and Wear OS rely on their own mapping services. Check the platform's app store to see which navigation apps are available before you choose a watch.

What to look for in a route-following watch

If following saved routes is important to you, look for a watch with built-in GPS, a screen that is readable outdoors, and a battery that can outlast your longest outing. See our guide to GPS smartwatches for models with reliable tracking. For hiking specifically, our hiking smartwatch guide covers features like altimeter and breadcrumb navigation.

Also check whether the watch supports offline maps. Not all do, and offline map storage takes up space. On Wear OS, offline maps from Google Maps are available, but you need to download the map area to your phone first. The Apple Watch Compass app works without a phone nearby but does not show street-level map tiles in the same way.

Finally, think about the apps you already use. If you track workouts with Strava, choose a watch that syncs with Strava. If you prefer AllTrails for trail discovery, make sure the watch platform has an AllTrails app. This keeps your routes and activity history in one place.

Choosing a watch for route following

The right watch depends on where you plan to follow routes. For city streets and turn-by-turn directions, a Wear OS watch with Google Maps or an Apple Watch with the Maps app works well. For off-trail hiking, look for a watch with breadcrumb navigation, a compass, and an altimeter. The best rugged GPS smartwatches often include these features.

For cycling, some watches pair with external sensors and show course points more prominently. If you race, a watch with preloaded courses and a race predictor can help. In all cases, confirm that the watch you like supports the route import method you plan to use, whether that is a GPX file, an app sync, or a built-in waypoint tool.

What to pick for your use

Questions

Can I follow a saved route without a phone signal?

Yes. Once the route is synced to the watch, the watch uses GPS to find your position. Offline maps make map tiles available without a signal, but the route guidance works even without them. GPS itself is a free service provided by the government and does not depend on a cellular network.

What file format do smartwatches use for routes?

GPX is the most common format. Most watch companion app can import GPX files directly. Some apps also accept other formats, but GPX is widely supported.

Do I need a separate app to create a route?

Not necessarily. Some watch platforms let you create waypoints on the watch, like Apple's Compass. For a planned route with many waypoints, using a phone app or online mapping service is easier. The app then syncs to the watch.

What is the difference between a route and a breadcrumb trail?

A route is a planned path with waypoints. A breadcrumb trail is a visual line that shows the path you've taken, usually from GPS tracking. Many watches combine both: you can follow a route, and the breadcrumb trail shows your actual path so you can return the same way.

Can I get turn-by-turn directions on any smartwatch?

Turn-by-turn directions are available on Wear OS and Apple Watch through Google Maps or Apple Maps. Many outdoor watches use breadcrumb navigation instead, which is a line on a map without spoken or arrow-based directions. The right choice depends on where you navigate.
