How to Change Activity Type in a FIT File: Fix Wrong Sport Classification
Learn how to change the activity type in a Garmin FIT file. Fix incorrectly detected sport types like running vs hiking, road vs trail cycling, and more.
How do you change the activity type in a FIT file? Open your file in the FIT File Editor, find the Activity Metadata section, select the correct sport type from the dropdown, then download your corrected file. The activity will now be properly classified in Garmin Connect, Strava, and other platforms.
Your fitness device tries to automatically detect what sport you're doing, but it doesn't always get it right. A slow trail run might be classified as a hike, or your gravel ride could be recorded as mountain biking. Here's how to fix it.
Why Activity Type Matters
The sport classification in your FIT file affects more than just how the activity appears:
Training Analysis Impact
| Affected Feature | How It's Impacted |
|---|---|
| Training Load | Different sports have different load calculations |
| Recovery Time | Running vs walking affects recovery predictions |
| Heart Rate Zones | Sport-specific zones are applied differently |
| VO2 Max Estimation | Only certain activities contribute to estimates |
| Training Status | Your overall training status assessment |
Platform Display
- Garmin Connect: Activity icons and categories
- Strava: Sport filters and segment matching
- TrainingPeaks: Workout categorization and TSS calculation
- Annual Statistics: Activities grouped by sport
Why Garmin Gets Sport Type Wrong
Understanding why auto-detection fails helps prevent future issues:
Speed-Based Detection
Many devices use speed as a primary indicator:
| Your Activity | Detected As | Why |
|---|---|---|
| Slow trail run | Walk or Hike | Speed below running threshold |
| Fast hike | Running | Speed above hiking threshold |
| Recovery run | Walking | Very slow pace |
| Pushing stroller | Walking | Slower than normal running |
Movement Pattern Confusion
| Your Activity | Detected As | Why |
|---|---|---|
| Hiking with poles | Nordic Walking | Arm movement pattern |
| Gravel riding | Mountain Biking | Surface and terrain |
| Indoor cycling | Training | No GPS movement |
| Treadmill running | Indoor Run | Correctly detected, but wrong sub-sport |
Device Limitations
- No auto-detect enabled: You started with wrong profile
- Profile not created: Device defaulted to "Other"
- Multi-sport confusion: Transition between sports

|---|---|
| Sport field | Updated to your selection |
| Sub-sport field | Updated if selected |
| Activity display | New icon and category |
| Platform categorization | Sorted correctly |
What Stays the Same
| Data | Status |
|---|---|
| GPS data | Unchanged |
| Heart rate | Preserved |
| Power/cadence | Maintained |
| Timestamps | Identical |
| Distance | Same calculation |
Platform Recalculations
Some platforms will recalculate metrics based on the new sport type:
- Training Load: May change based on sport intensity factors
- Calories: Adjusted for sport-specific calculations
- Training Effect: Recalculated for new sport type
Common Scenarios and Solutions
Scenario 1: Trail Run Detected as Hike
Problem: Your mountain trail run was slow due to terrain, and Garmin marked it as a hike.
Solution:
- Change sport type to "Running"
- Set sub-sport to "Trail"
- Your running metrics and training load will be correct
Scenario 2: Gravel Ride Marked as Mountain Bike
Problem: Your gravel bike ride shows as mountain biking.
Solution:
- Change sport type to "Cycling"
- Set sub-sport to "Gravel"
- Strava segments will match correctly
Scenario 3: Indoor Activity Without GPS
Problem: Your treadmill run shows as "Training" or "Indoor"
Solution:
- Change to "Running"
- Set sub-sport to "Treadmill"
- Running stats and VO2 Max may now update
Scenario 4: Wrong Profile Started
Problem: You pressed the wrong activity button on your watch.
Solution:
- Change to the correct sport type
- All your data is preserved
- Only the classification changes
Alternative: Editing in Platforms
Some platforms allow limited sport type changes:
Garmin Connect
- Open the activity
- Click the pencil/edit icon
- Change "Activity Type" dropdown
- Save changes
Limitation: Changes only affect Garmin Connect display, not the source file.
Strava
- Open the activity
- Click the pencil icon
- Change "Sport" type
- Save
Limitation: Doesn't change the original file; only Strava's copy.
When to Edit the Source File
Use the FIT File Editor when you need:
- Changes to persist across all platforms
- To archive a corrected file
- To re-upload to multiple services
- The original file for training analysis software
Preventing Wrong Classifications
Tips to get the right sport type from the start:
Before Your Activity
- Create activity profiles: Set up profiles for each sport you do
- Start manually: Don't rely on auto-detect for unusual activities
- Check before starting: Verify the correct sport is selected
- Update device: Latest firmware improves auto-detection
Configure Auto-Detection
On most Garmin devices:
- Go to Settings > Activities & Apps
- Select the activity
- Adjust auto-detect settings
- Set speed thresholds if available

Frequently Asked Questions
Will changing sport type affect my training load history?
Yes, when you re-upload the corrected file, your training load will be recalculated based on the correct sport type.
Can I change an activity to multisport?
Yes, you can set the sport type to "Multisport," but individual transition and sport segments within the activity won't be created—that requires recording as multisport originally.
Does this work for activities from any device?
Yes, the FIT format is standardized. Files from Garmin, Wahoo, COROS, Suunto, and other devices can all have their sport type changed.
Will Garmin Connect accept the edited file?
Yes. The edited FIT file is fully compatible with Garmin Connect. You can upload it as a new activity or delete the old one and re-upload.
Can I change the activity name too?
Yes! The Activity Metadata section also lets you change the activity name (title) that appears in platforms.
