COROS and AllTrails announced a new integration on Monday that links the watchmaker’s GPS devices with one of the largest trail databases in the world. For trail runners, the practical result is fewer apps to juggle before a long run and a cleaner record of where they have been.
The two companies said members can now plan a route in AllTrails, push it to a COROS watch, and follow turn-by-turn directions on the wrist. Once the run is done, the activity syncs back to AllTrails, where users can post photos, leave trail reviews, and contribute to community-verified trail data.
“We’re excited to make it easier for COROS users to find, save, and navigate routes from AllTrails with this new integration. AllTrails is one of the global leaders in mapping and outdoor route finding, and adding this integration means more COROS users can confidently explore the outdoors.”
Darian Allberry, Head of Product Marketing at COROS

What runners actually get
The integration covers four main functions. Activities recorded on a COROS device sync back to AllTrails, so a runner’s adventure log lives in one place. Any route saved through an AllTrails Plus or AllTrails Peak subscription can be sent to a COROS watch for hands-free navigation. Runners can plan with community trail data and then follow that plan on the watch. They can also leave reviews and photos on AllTrails for activities the watch recorded.
Before this, most COROS users who relied on AllTrails had to export GPX files manually or run a third-party sync tool. That extra step is the kind of thing that gets skipped on race morning or after a hard 20-miler when uploading photos is the last thing anyone wants to do. If you’re new to navigating off-road, our trail running for beginners guide is a good place to start, and our roundup of route mapping tools covers how AllTrails stacks up against the alternatives.

Why this matters for the trail community
AllTrails framed the partnership as a way to keep its users looking at the trail rather than at a phone screen.
“At AllTrails, we believe the best technology gets you off your screen and into the outdoors. Partnering with COROS gives our community a seamless experience from route discovery to the trailhead, with devices our members love and trust.”
Kai Twanmoh, Senior Director of Brand Engagement at AllTrails
Trail runners have been one of the fastest-growing groups of buyers for both brands. COROS built its reputation in the ultrarunning world with watches like the Apex and Vertix, both popular at events such as the Western States 100 and UTMB. Readers comparing models can check our COROS APEX review and our COROS vs Garmin breakdown for context. AllTrails, meanwhile, has become a default reference for runners scoping out unfamiliar terrain on travel or training camps.

The companies did not share user numbers tied to the integration or a timeline for additional features. Setup instructions are posted on the COROS and AllTrails support pages.
