A GPX file is a standard GPS format that works with all running watches and apps. It contains waypoints that guide you along the heart-shaped route, turn by turn.

Which devices are compatible?

CityHeart routes work with Garmin, Apple Watch (via WorkOutDoors or Strava), Coros, Suunto, Polar, and any app that imports GPX files like Strava, Komoot, or AllTrails.

How do I load the GPX on my watch?

For Garmin: upload via Garmin Connect. For Apple Watch: use the Strava or WorkOutDoors app. For Coros: import through the Coros app. Each takes under 2 minutes.

Can I modify the route after purchase?

Yes! Use our free route editor to adjust the start point, distance, or shape. You can also re-generate a new heart in the same city at no extra cost.

Can I gift a heart route to someone who runs?

Yes. Use the gift option at checkout: they get a personal gift page and GPX in their city — ideal for Valentine's Day, birthdays, and anniversaries.

How accurate is the heart shape?

The route follows real roads, so it won't be mathematically perfect. But viewed on Strava or Garmin, the shape is clearly recognizable as a heart — that's the magic of GPS art.
