Overview

Create "program" outside Coxswain.

a program can be create within coxswain but the limitation of this prevent sometime the ability to create specific program. E.g Beginer Pete Plan has some custom distance (750m) or the upper limit of 10000m, which can't be create within coswain as the distance increase only allow 100m steps.

But in order to achieve that it is possible to edit the program file. Such a file can be open with notepad in Windows and every text file program within linux e.g vim, emacs, nano, gedit.

This is how a program file looks like. This program is called "all option" and has 4 segments with all possible settings. Next will be an explanation of each line.

{
  "name": "all option",
  "segments": [
    {
      "difficulty": "MEDIUM",
      "energy": 10,
      "speed": 10
    },
    {
      "difficulty": "HARD",
      "strokes": 5,
      "pulse": 1
    },
    {
      "difficulty": "EASY",
      "duration": 30,
      "strokeRate": 1
    },
    {
      "difficulty": "EASY",
      "distance": 250,
      "power": 10
    }
  ]
}

this is the program name

"name": "all option",

This is the start of all the upcoming segments which are going to be defined

  "segments": [

this is the first segment of the file.

  • difficulty corresponds to color bar on the left side of the program. Green = easy, Yellow = medium, Orange = hard
  • "energy" in this case is the target which is going to be count down for this segment.
  • "speed" is the target to maintain during this segment
    {
      "difficulty": "MEDIUM",
      "energy": 10,
      "speed": 10
    },

So it is possible to create custom program which only need to be imported to Coxswain. This is then available as new program.

Analyze the workout

Import to Garmin connect, Strava, google fit

It is possible to just upload a tcx file to Garmin connnect, Strava and google fit. The time which is recorded within a tcx workout file is UTC + 0. This must be change to your timezone by hand once uploaded to the different websites. Garmin connect also won't recognize the Waterrower as erg or rowing. This must also be updated manually.
