Writing data
Learn how to write data back to providers, and create a bi-directional data stream between your app and the various integrations you connect to
Terra allows you to write data back to a user's account, wherever supported by the respective Provider.
Writing Planned Workouts
Overview
Writing planned workouts allows you to create a workout plan for the user (such as those commonly used with Zwift)
This will typically look like the following example:
Planned workouts consist of a series of steps. Each step has:
Completion criteria (called duration for all intents and purposes). For example:
distance (keep going until you cover 500m),
energy expenditure (keep going until you burn 200 kcal)
heart rate threshold (keep going until your heart rate reaches above 150 bpm)
etc..
One or more targets to be maintained
heart rate (maintain heart rate between certain bounds)
speed (maintain speed between certain bounds)
grade (inclination above a certain threshold)
etc...
An associated intensity label
Warmup
Active
Cooldown
etc..
An exercise type
Running
Cycling
Deadlifting
etc...
A series of sub-steps
These modalities allow any workout to be described in a series of defined steps for each of its segments.
Once written, a planned workout will be available in the user's library of workouts on the respective platform, and the user will then be able to follow the workout step by step on their wearable device
Writing Planned Workouts
Supported providers
Currently supported providers are:
Garmin
Hammerhead
Coros
TodaysPlan
See the Supported integrations page for a full list of supported data types per Provider
Usage
In order to write a planned workout to the user's device, you may use the following endpoint
The response will include log_ids which will be a list of the identifiers for the uploaded workout plans. You may use those identifiers to identify the workout plan later on in the REST API Endpointsendpoint, or to delete them using the REST API Endpoints
Examples
Aerobic fitness test
The aerobic fitness test begins with a 5 minute warm-up.
After warming up, the intensity will ramp up over the duration of 5 minutes, reaching a 91% max HR intensity.
Once you are done with the all out effort, you will spend 2 minutes in a recovery step, before spending 5 minutes cooling down
