COROS AllTrails Integration Reviewed: Functional but Behind Garmin

COROS watches now sync directly with AllTrails for paid subscribers. No more exporting GPX files by hand, copying them over, and hoping the route loads cleanly on your wrist. That friction point is gone. But gone is not the same as polished, and this integration still asks more of you than Garmin's equivalent does.

How the Integration Actually Works

The setup links your COROS account to AllTrails through the COROS app. Once connected, saved AllTrails routes appear inside the COROS app and can be sent to your watch. The sync is real and functional. The catch is that you still need to manually open the app, navigate to the route, and push it to your device before heading out. Garmin's ConnectIQ-based AllTrails integration handles more of that flow automatically, with tighter background sync that requires fewer deliberate steps from the athlete. For a runner grabbing their watch five minutes before a trail run, that difference matters.

The navigation on-watch is driven by GPS satellite positioning, same as any route-following feature on Coros, Garmin, or Polar. Your watch is tracking your position against a loaded breadcrumb line. What changes here is where that breadcrumb line comes from: AllTrails' database instead of a self-recorded or manually imported file. That is genuinely useful for trail runners who discover routes on AllTrails and want them on their wrist without a laptop involved.

Who Actually Benefits Here

Trail runners and ultrarunners get the most from this. If you spend time on AllTrails browsing community-verified routes, saving a handful for an upcoming trip, and then racing out the door with a COROS Vertix 2S or Pace 3 on your wrist, the old workflow was genuinely annoying. Download GPX, find the file, import manually. That's three steps this integration collapses into one. For road runners or cyclists who rarely touch AllTrails, this update changes nothing about their daily experience.

Hyrox and CrossFit athletes won't care at all. Triathletes training on open roads or marked courses are similarly unaffected. This is a trail-specific quality-of-life fix, and it should be read as exactly that. COROS has been expanding its ecosystem integrations steadily in 2026, including [a data partnership with Wahoo](/en/articles/coros-and-wahoo-partner-on-data-sync-and-hardware-reselling-2026-05-16) and [opening its data pipeline to AI platforms](/en/articles/coros-opens-data-gates-to-ai-2026-05-15), so AllTrails fits a clear pattern of catching up on connectivity.

Comparing COROS and Garmin on Ecosystem Depth

Garmin has held a substantial lead in third-party integrations for years. Connect IQ, Garmin's app platform, supports deeper hooks into partner apps than COROS currently offers. The AllTrails gap is one example. Garmin watches like the Fenix 8 or Forerunner 965 can complete more of the route-loading workflow in the background without requiring the user to actively manage it. COROS is catching up, but catching up is different from being equal. That said, COROS hardware competes hard on battery life and GPS accuracy at its price points. A Pace 3 at around 250 dollars beats several Garmin watches costing 100 dollars more on multiband GPS endurance. The software ecosystem has historically been where COROS trails.

Polar and Suunto are not really in this conversation. Neither has AllTrails integration at the same level, and both have narrower third-party app ecosystems overall. Whoop has no GPS or navigation features at all, so it sits in a different category entirely. The real benchmark for COROS AllTrails is Garmin, and by that benchmark COROS is one step closer but not yet level. Brand loyalty dynamics in 2026 are worth watching here too: [data suggests Garmin and COROS owners are among the most likely to switch brands this year](/en/articles/garmin-and-coros-owners-most-likely-to-switch-brands-in-2026-2026-06-09), which makes ecosystem parity increasingly important for retention.

What's missing is background sync and a more seamless handoff between the AllTrails app and the watch. The current implementation still feels like a bridge solution rather than a native-feeling feature. There is also no AllTrails discovery inside the COROS app itself. You find routes in AllTrails, save them there, and then access them through COROS. That two-app dance is a minor annoyance but a real one, especially compared to how fluid Garmin's routing ecosystem feels after years of refinement. Paid AllTrails subscription required is also worth flagging plainly: this does nothing for free-tier AllTrails users.

Bottom line: if you are a trail runner on COROS hardware who pays for AllTrails, this update removes a real friction point and you should use it today. If you are choosing between a COROS Vertix 2S and a Garmin Fenix 8 specifically because of route navigation workflow, Garmin still wins on ecosystem smoothness. The COROS hardware case, battery life, price, GPS quality, remains strong. The software is getting better at a steady pace, just not at a pace that has closed the gap yet.
