GPS Fixes
Clean up route anomalies, drift, or short sections where the original trace no longer reflects the activity as expected.
Metric Control
Adjust pace, heart rate, watts, and related workout fields when the file needs more consistent structured data.
Better Imports
Prepare a file that is easier to re-import into your broader training workflow with route and metrics kept together.
What Is a TCX/GPX File?
A GPX or TCX file is the portable record of an activity. It stores the route as a series of GPS points so another platform can recreate where the activity happened. If you only need the map shape, GPX is often enough. It is lightweight, common, and works well for route geometry.
TCX goes further. In addition to the path, it can carry workout data such as timestamps, pace, heart rate, cadence, and watts. That is why many editing workflows start with TCX when the goal is not just to change where the route goes, but also how the activity behaves inside training analysis tools. If you need to create a file from scratch, ForgePace also offers a GPX generator and a TCX generator.
How to Edit a Strava Activity File Step by Step
1. Export the activity from Strava
Open your account settings and activity export options, then download the activity file you want to work on. This gives you the original track data so you can make changes outside the platform.
2. Upload it to ForgePace Upload & Boost
Bring the exported file into ForgePace. The tool is designed to work with TCX activity files when you want a controlled way to adjust route structure and workout metrics in one place.
3. Select the segment to modify
Choose the portion of the activity that needs attention. This is useful when the goal is to fix a single section instead of replacing the entire workout file from start to finish.
4. Download and re-import
Once the edits are applied, export the updated file and import it back into your training workflow. The result is a cleaner activity file with the route and metrics adjusted together.
This process keeps the workflow simple: export, edit, and import again. It is especially useful when a route file needs a targeted adjustment rather than a full rebuild. Because ForgePace focuses on the file itself, you can work with both route shape and the activity metrics that depend on it, instead of treating them as separate tasks.
For teams, coaches, or athletes comparing multiple file formats, it also helps to understand when to stay with GPX and when to move to TCX. Route-only edits are often straightforward in GPX, while more structured adjustments benefit from TCX because the workout fields travel with the route data.
FAQ
Can I edit a Strava activity after upload?
You can edit some activity details directly in Strava, such as the title, sport type, or gear, but deeper file-level changes usually require exporting the activity, editing the file, and importing the updated version again.
What file formats does Strava support?
Strava commonly supports GPX, TCX, and FIT files for imports. GPX is widely used for route geometry, while TCX is often preferred when you want to keep workout fields such as pace, heart rate, or power aligned with the route.
What is the difference between GPX and TCX?
A GPX file is mainly about GPS track points and route shape. A TCX file can also include structured workout data such as timestamps, pace, heart rate, cadence, and watts, which makes it more flexible for activity editing workflows.
Why use ForgePace as a Strava activity editor?
ForgePace is useful when you need a simple web workflow: upload a TCX file, adjust the part of the activity you want to change, then download an updated file ready for import.
