How to Convert GPX to FIT: Step-by-Step
Step 1: Get Your GPX File
From Komoot:
- Open your planned tour
- Click "More" → "Download GPX"

From RideWithGPS:
- Open the route

Step 3: Set Your Average Speed
This is the key step that differs from other conversions:
Why speed is required:
- GPX route files typically don't include timing data
- FIT files need timestamps for each point
- The speed you enter determines calculated timing
Recommended speeds:
| Activity | Average Speed |
|---|---|
| Walking | 4-5 km/h |
| Hiking (moderate) | 4-6 km/h |
| Running (easy) | 8-10 km/h |
| Running (moderate) | 10-12 km/h |
| Cycling (casual) | 15-20 km/h |
| Cycling (road) | 25-35 km/h |
| Mountain biking | 12-20 km/h |
Tip: The speed doesn't affect navigation—it only influences estimated timing. Choose a realistic average for your activity type.
Step 4: Convert and Download
- Click the "Convert" button
- Processing happens instantly in your browser
- Download your converted FIT file
Step 5: Upload to Your Garmin
Via Garmin Connect (recommended):

Understanding Speed Settings
The average speed you set affects:
What It Affects
- Estimated finish time shown on device
- Pace/speed targets during navigation
- Virtual partner timing (if used)
What It Doesn't Affect
- The actual route (coordinates are unchanged)
- Turn-by-turn directions (if supported)
- Elevation data (preserved from GPX)
- Distance (calculated from coordinates)
Choosing the Right Speed
Consider these factors:
- Terrain: Hills slow you down—lower your average
- Fitness level: Be realistic about your pace
- Activity type: Different sports have different typical speeds
- Conditions: Wind, heat, or technical trails affect speed
Example: For a hilly cycling route you'd normally average 22 km/h on flat roads, you might enter 18-20 km/h to account for climbing.

Common Questions
Why does the converter ask for speed?
GPX route files don't include timing information—they're just a list of coordinates. FIT files require timestamps, so we calculate them based on your average speed. This doesn't affect the route itself, only the timing estimates.
Will navigation work on my Garmin?
Navigation depends on your specific device model. Most Edge bike computers and newer Forerunner watches support course navigation with turn prompts. The converted FIT file contains all necessary route data.
Can I convert routes with waypoints?
Yes, waypoints from your GPX file are included in the FIT file as course points. These appear as markers along your route.
What if my GPX has multiple tracks?
The converter combines all tracks into a single course. If you need separate courses, split the GPX file first using a GPX editor.
Does elevation data transfer?
Yes, if your GPX file includes elevation data, it's preserved in the FIT file. Your Garmin will show the elevation profile during navigation.
Troubleshooting
Route doesn't appear on device
- Verify the file uploaded to Garmin Connect
- Check device is synced
- Look in Courses/Navigation section
- Try syncing again
Wrong activity type shown
The FIT file includes activity type metadata. If incorrect, you can usually change this in Garmin Connect after upload.
Estimated time seems wrong
Adjust the average speed in the converter. Remember to account for terrain—hills slow you down significantly.
