WKO5 New Install Setup Wizard

Download WKO

Try WKO free for 14 days before you buy! There are no limitations to the trial; you'll get the full software. Simply click here, choose your operating system, click the Download button, and launch the installer.

Welcome to WKO

This screen introduces the installation wizard and highlights some important tips. Please note that you will need your TrainingPeaks user name and password to install WKO, even if you do not plan to sync WKO with a TrainingPeaks account.

Choose a Data Folder

WKO will automatically create a data folder named WKO5 in a suggested data store location. It is NOT recommended to store your data in your Documents folder due to cloud storage; if the wizard automatically places the folder in Documents, click the ... button to select your user folder instead (the folder in which the Documents folder is contained).


Please note that WKO does not support data storage in cloud folders (such as OneDrive, Dropbox, and iCloud), and storing your data in the cloud can cause significant issues. The standard Documents folder on both Mac and PC is synced to the cloud by default, so be sure not to store your data folder in Documents.

Initial Preferences

This screen allows you to set a few preferences before you even launch the software. Choose whether WKO uses metric or English units of measurements, the day on which your training week begins, and whether you want your default view to include charts for cycling, running, or multisport. 


Please note that you will have access to all WKO charts no matter which option you choose; this simply determines which charts are initially shown on your screen when you first install the software.

Start Trial or Activate WKO

WKO should now be open on your screen and beginning its first sync with TrainingPeaks. You will be prompted to enter your TrainingPeaks user name and password, create a name for your computer, and enter your registration code to active the software. If you are still within your trial period, you can click Continue Trial without entering a registration code.

Complete First Download

The first time WKO downloads from TrainingPeaks can take quite a bit of time, depending on how many years of workouts are in your TrainingPeaks account and/or how many athletes are connected to your TrainingPeaks coach account. Be sure to allow the first download to complete before closing WKO. We recommend setting your computer to stay awake and not power off or sleep until the download is complete.


If the download is interrupted for any reason, you may need to perform another full download to finish importing all the workouts.


WKO Upgrade from WKO4

Upgrading to WKO5 from WKO4 is unique from starting with WKO5 as a brand new user. If you are already using WKO4, WKO5 is essentially a new build of your existing software, not a new application. WKO5 shares your WKO4 data and imports it into its own process.

Please read the following instructions carefully before installing WKO5.

Download WKO5

Try WKO free for 14 days before you buy! There are no limitations to the trial; you'll get the full software. Simply click here, choose your operating system, click the Download button, and launch the installer.

Important Upgrade Information

WKO5 is designed as an update of WKO4, but it does not consume WKO4; they are separate apps. WKO5 shares your WKO4 data and translates it into WKO5. We do not recommend using both WKO4 and WKO5 at the same time, as it can cause errors and duplicates within your data. 


Please note that you will need your TrainingPeaks user name and password to install WKO, even if you do not plan to sync WKO with a TrainingPeaks account.

Back Up Your WKO4 Data

It's important to back up data before making any change to your computer, and installing WKO5 is no exception. Before upgrading, follow these instructions to make a backup copy of your WKO4 data folder:


  1. Close WKO4.
  2. Using Finder/Explorer, navigate to the folder containing your WKO4 data. This will typically be found in your Documents folder on PC (UserName > Documents) or your user account folder on Mac (ComputerName > UserName). If you aren’t sure where the folder is stored, open WKO4, open Preferences, make note of the location given in the Data store location field, and close WKO4 again.
  3. Right-click the data folder (named WKO4) and click Copy. 
  4. Navigate to your Desktop, right-click, and paste a copy of the data folder. 
  5. Rename this folder to WKO4backup.

Choose a Data Folder

The second screen of the installation wizard will ask you to select a data folder. Since a WKO4 data folder already exists, WKO will automatically select it. 


If you do not wish to use your WKO4 data folder, click "Use Default Location" to create a new, separate data folder.

Confirm Installation

Enter your TrainingPeaks user name and password, wait for WKO to log in, and click Finished.


Note: The user name and password fields are limited to 50 characters.

Start Trial or Activate WKO

You will be prompted to enter your TrainingPeaks user name and password, create a name for your computer, and enter your registration code to active the software. If you are still within your trial period, you can click Continue Trial without entering a registration code.

Compile Data and Download

WKO can take quite a bit of time to finish importing your WKO4 data and downloading data from TrainingPeaks, depending on how many athletes and years of data you have. Be sure to allow the compiling and first sync to complete before closing WKO. We recommend setting your computer to stay awake and not power off or sleep until the process is complete.
