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 FeatureHow It's Impacted
Training LoadDifferent sports have different load calculations
Recovery TimeRunning vs walking affects recovery predictions
Heart Rate ZonesSport-specific zones are applied differently
VO2 Max EstimationOnly certain activities contribute to estimates
Training StatusYour 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 ActivityDetected AsWhy
Slow trail runWalk or HikeSpeed below running threshold
Fast hikeRunningSpeed above hiking threshold
Recovery runWalkingVery slow pace
Pushing strollerWalkingSlower than normal running

Movement Pattern Confusion

Your ActivityDetected AsWhy
Hiking with polesNordic WalkingArm movement pattern
Gravel ridingMountain BikingSurface and terrain
Indoor cyclingTrainingNo GPS movement
Treadmill runningIndoor RunCorrectly 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

  • 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:

  1. Change sport type to "Running"
  2. Set sub-sport to "Trail"
  3. 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:

  1. Change sport type to "Cycling"
  2. Set sub-sport to "Gravel"
  3. Strava segments will match correctly

Scenario 3: Indoor Activity Without GPS

Problem: Your treadmill run shows as "Training" or "Indoor"

Solution:

  1. Change to "Running"
  2. Set sub-sport to "Treadmill"
  3. Running stats and VO2 Max may now update

Scenario 4: Wrong Profile Started

Problem: You pressed the wrong activity button on your watch.

Solution:

  1. Change to the correct sport type
  2. All your data is preserved
  3. Only the classification changes

Alternative: Editing in Platforms

Some platforms allow limited sport type changes:

Garmin Connect

  1. Open the activity
  2. Click the pencil/edit icon
  3. Change "Activity Type" dropdown
  4. Save changes

Limitation: Changes only affect Garmin Connect display, not the source file.

Strava

  1. Open the activity
  2. Click the pencil icon
  3. Change "Sport" type
  4. 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

  1. Create activity profiles: Set up profiles for each sport you do
  2. Start manually: Don't rely on auto-detect for unusual activities
  3. Check before starting: Verify the correct sport is selected
  4. Update device: Latest firmware improves auto-detection

Configure Auto-Detection

On most Garmin devices:

  1. Go to Settings > Activities & Apps
  2. Select the activity
  3. Adjust auto-detect settings
  4. Set speed thresholds if available

Understanding FIT Files

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.
