Garmin + Trailia: The Deepest Data Your Watch Collects, Finally Put to Work

Connect your Garmin Connect account and Trailia reads your heart rate, FIT files, and real-time webhooks to build trail training plans from your most precise data.

Garmin records more than any other device most trail runners own: heart rate time-series, cadence, elevation, strength workout data, FIT files with raw sensor readings. Connect your Garmin Connect account and Trailia pulls all of it in real time.

What Syncs from Garmin Connect

Trailia connects via Garmin's official OAuth 2.0 API with real-time webhooks, so data arrives within minutes of your activity ending. On first connection, 30 days of activity history imports automatically.

Data synced: Heart rate time-series, FIT file parsing, Elevation gain, Cadence, Strength workouts.

Key Features

Real-time activity sync via webhooks

Garmin pushes data to Trailia the moment your activity uploads. Your calendar and training load update within minutes of finishing a run.

Training load tracked from real heart rate

Because every Garmin activity arrives with accurate heart rate and duration, Trailia tracks your training load and the balance between recent and longer-term work rather than estimating it from distance.

Full FIT file analysis

Garmin's FIT format contains far more data than what appears in activity summaries: per-second heart rate, raw GPS coordinates, running dynamics.

Training load and ACWR tracking

With precise heart rate and duration data from every Garmin activity, Trailia computes your ACWR accurately.

Strength workout data

If you log strength sessions on your Garmin, Trailia imports those too.

Workout reviews from your real data

After a key session, Trailia compares your Garmin data against the planned targets.
