Calibrate TRIPS with FIT files

Use this article when you want the full calibration workflow in one place.

The calibration workflow

1. Decide whether calibration is worth doing.
2. Prepare a FIT folder.
3. Choose which FIT files to include.
4. Ingest the FIT files.
5. Understand any ingest warnings.
6. Review calibration outputs.
7. Preview how the calibration changes route behavior.
8. Save a profile if the result looks better.
9. Apply the profile to a route and compare before and after.

Step 1: Decide whether to calibrate

Calibration is optional.

If you are still learning the planner, start without calibration first.

Step 2: Prepare a FIT folder

You will get better results if the folder mostly contains activities that resemble the trips you want to plan.

• Prepare a FIT folder for calibration before ingest

Step 3: Choose which FIT files to include

Do not think only about quantity.

Think about relevance and representativeness too.

• Which FIT files should I include for calibration? for the decision rules

Step 4: Ingest the files

Once the folder is ready, use the calibration ingest workflow to build the local dataset snapshot.

Step 5: Interpret warnings before continuing

The ingest preflight is there to help you decide whether this folder is practical in the current browser session.

• Understand FIT ingest warnings if the warning state is unclear

Step 6: Review the resulting calibration outputs

Do not assume a completed ingest automatically means the dataset is good enough.

Review the outputs and ask whether they look representative and believable.

Step 7: Compare route behavior before and after

Use preview to compare the same route with and without the calibration.

If the changes make the planner feel more realistic, keep going.

If they make things less believable, do not force it.

Step 8: Save and apply deliberately

If the calibration looks useful:

• save it as a profile
• assign it to the current trip or future trips
