Which of these is you?

Indoor distance goes wrong in a few specific ways. Each one has its own answer, and not all of them need an app.

The watch and the treadmill disagree

Why the two numbers drift apart, and which one to trust before you correct anything.

You want to edit a saved workout

What Apple actually allows, why HealthKit will not edit distance in place, and what a corrected copy means.

Indoor runs are always off

Calibration, arm movement and the limits of wrist-based distance estimation.

A focused Apple Health workflow

Choose recorded or reliable GPS distance, correct supported elevation, and review FIT imports. Export FIT, GPX, TCX, CSV or JSON; GPX needs a usable route. GPS points are never invented.

Review the original workout before saving.
Compare original and corrected distance.
Save prepares and checks a corrected copy. Review any additional omission or estimate; HealthKit limits which data can be copied. Originals stay unchanged.

FAQ

Can I edit Apple Watch workout distance directly?

Apple Health does not offer a simple direct distance edit. Fix My Workout saves a corrected workout copy instead.

Does it work offline?

The correction flow is local to your device and Apple Health permissions. App Store purchase actions require Apple services.

Is my workout data tracked?

Workout processing stays on-device. TelemetryDeck receives product events without health data. Exports and diagnostics are shared only when you choose.
