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.

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.

Heart Running Battle — Amsterdam vs Berlin

A heart run battle compares heart-shaped GPS art routes between two cities to determine which one offers the best running experience.

Each city's unique street layout creates a distinctive heart shape that reflects its character — from wide European boulevards to narrow historic alleyways.

Whether you're planning a destination race, a weekend city break, or a training run abroad, this battle helps you decide which city deserves your next heart-shaped GPS art run. Both Amsterdam and Berlin routes are available as instant GPX downloads compatible with Garmin, Apple Watch, Coros, Suunto, and Strava.
