Units

Most units in the API are SI (International System of Units) units.

Location and Sensor Points

Due to the possible large amount of data related to location and sensor data, uses offset/value pairs. For example:

[offset_1, value_1, offset_2, value_2, ... offset_n, value_n]

The offset will always be an integer with the range [0, ∞). It is the number of seconds after the workout start_time. The datatype of the 'value' changes based on which type of track it is. Right now, there are four possible tracks:

  • location - array of decimal degrees latitude (index 0) and decimal degrees longitude (index 1))
  • elevation - real number (meters)
  • distance - real number (meters)
  • heartrate - integer (bpm)

ISO 8601 DateTime

A full date time string conforming with ISO 8601 with any of the forms:

  • 2012-04-23T13:12Z (UTC timezone)
  • 2012-04-23T13:12-05:00
  • 2012-04-23T13:12-0500
  • 2012-04-23T13:12-05

Workout Type

An enum of possible workout types. If the workout type does not have a analogue in SportTracks, use the type 'Other' and set the name property. The current types (case insensitive) are:

  • Cycling
  • Hiking
  • Rowing
  • Running
  • Skating
  • Skiing
  • Swimming
  • Walking
  • Gym
  • Other

To set the sub-type, use a colon (':') and then the subtype. For examples:

  • Cycling:Hills
  • Cycling:Trainer
  • Cycling:Spinning
  • Gym:Plyometrics
  • Gym:Stretching
  • Other:Golf
  • Other:Climbing

Sharing Type

An enum of possible workout sharing types:

  • public
  • friends
  • private

Lap Type

An enum of possible lap types. Used to indicate if the lap was recorded or not.

  • ACTIVE
  • REST

Timer Stops

A timer stop is an array of ISO 8601 DateTimes. Index 0 is the start of the pause, and index 1 is the end of the pause.
