Format Comparison

GPX vs TCX : Which Format Should You Use?

The GPX vs TCX question usually comes down to one decision: do you mainly need a route, or do you need a richer activity record? GPX is centered on GPS structure. It is commonly used for routes, waypoints, and track lines that can move easily between mapping tools and navigation devices. If your main goal is to create or share the path of a ride or run, GPX is often the simpler choice.

TCX, by contrast, stands for Training Center XML and is designed for activity data with more workout context. In addition to location points, a TCX file can describe elapsed time, lap structure, cadence, heart rate, and power. That makes it useful when you want the route and the metrics to stay connected in a training platform. For Strava-related workflows, the better format depends on whether you are prioritizing route geometry or performance fields.

In practical terms, GPX is strong for route planning, navigation, and moving a course between tools. TCX is stronger for structured activity imports where the file should carry training detail. If you are preparing a course, exporting a map-based path, or sharing a clean GPS line, GPX is usually enough. If you want an activity record with richer sensor context, TCX is the more capable option.

ForgePace supports both directions of that decision. You can use the GPX generator when route geometry is the priority, or move to the TCX generator when you need more detailed workout fields. The right choice is less about which format is “better” in general, and more about which one matches the destination platform and the data you want to preserve.

GPX vs TCX at a Glance

Category	GPX	TCX
Primary focus	GPS route geometry, waypoints, and track shape	Training activity structure plus route and time-based data
Metrics support	Limited for detailed workout fields	Better suited to heart rate, cadence, power, and laps
Best use case	Navigation, route sharing, and course planning	Workout review, structured imports, and richer activity context
Typical destination	Mapping apps, route planners, and GPS navigation devices	Training platforms and devices that benefit from XML activity metrics

When GPX Makes Sense

Choose GPX when the route itself is the important asset. It is a practical format for planning a course, sending a path to a navigation app, or keeping a route library that can move across multiple tools with minimal friction.

When TCX Makes Sense

Choose TCX when the file should describe the session in more detail. It is better suited to activity imports where metrics and timing matter, especially if the destination platform is expected to read more than raw GPS geometry.

FAQ

Is GPX or TCX better for Strava?

It depends on the goal. GPX is usually enough when you only need route geometry, while TCX is more appropriate when you want timestamps and training metrics such as heart rate, cadence, or power to travel with the activity.

What data does GPX usually contain?

GPX focuses on GPS structure: coordinates, route shape, waypoints, and track order. It is practical for navigation and route planning, but it is not the strongest format for detailed workout metrics.

What does TCX add on top of GPX?

TCX adds a training-oriented XML structure. In addition to route points, it can represent elapsed time, lap logic, cadence, heart rate, and power fields in workflows that depend on richer activity context.

When should I choose TCX over GPX?

Choose TCX when analysis matters as much as the path itself. If you want the file to carry workout metrics alongside the route, TCX is usually the better fit.
