NRC2Strava

This project exports run activities from Nike Run Club (NRC) and imports them into the Strava platform. It supports both outdoor and indoor run activities.

Initially, I used the project nrc-exporter to import my NRC runs. However, treadmill runs were not supported due to the limitations of the .gpx format. To address this, I started this project to convert NRC runs into the FIT format, which is more advanced and fully compatible with Strava.

Features:

• Downloads Nike Run Club activities and saves them to disk.
• Converts these activities from the .json format to the .fit format, compatible with the Strava platform.
• Handles both indoor (treadmill) and outdoor (GPS) runs.
• Uploads .fit activities to Strava without requiring you to create an app on the developer platform.

Requirements

• Go: Ensure you have Go installed on your system.

Step by Step

We will import the entire NRC activity history into Strava by following these steps.

0. Build

Clone and compile:

$ git clone git@github.com:mxdc/nrc2strava.git
$ cd nrc2strava
$ go mod tidy
$ go build -o bin/nrc2strava cmd/main.go

1. Download NRC Activities

Retrieve the NRC Token

To download activities from NRC, you need to obtain your Nike access token.

First, log in to Nike.com with your account using your web browser.

Then you have two options:

• Navigate to the Application tab, locate the oidc.user:https://accounts.nike.com:4fd2d5e7db76e0f85a6bb56721bd51df in the Local Storage, and copy the access_token.
• Or retrieve the token from the browser's developer console using the following command:

JSON.parse(window.localStorage.getItem('oidc.user:https://accounts.nike.com:4fd2d5e7db76e0f85a6bb56721bd51df')).access_token

Once you have the token, export it as an environment variable:

$ export NIKE_TOKEN='<access_token>'

Download NRC activities

Once you have the token, use the following command to download activities:

$ bin/nrc2strava download --activities.dir='./downloaded' --nrc.token="$NIKE_TOKEN"

This will save all activities as JSON files in the ./downloaded directory.

Convert JSON Activities to FIT Format

With all your activities now saved on disk as JSON files, you can convert them into FIT files:

$ bin/nrc2strava convert --activities.dir './downloaded' --fit.dir './output'

The FIT files will be saved in the ./output directory.

2. Upload FIT Activities to Strava

Retrieve the Strava Tokens

The Strava tokens are stored in the browser cookies.

Log in to the Strava.com with your account, open the developer console, navigate to the Application tab, and locate the _strava4_session cookie.

Export these values as environment variables:

$ export STRAVA4SESSION='<_strava4_session>'

Upload FIT Activities to Strava

Upload the FIT activities to Strava:

$ bin/nrc2strava upload --fit.dir='./output' --strava.token="$STRAVA4SESSION"

For each successful upload, the .fit file is moved into an uploaded subfolder. This way, you can run the command as many times as needed without worrying about uploading the same files multiple times.

If you have more than 600+ run activities like me, the Strava API will likely rate limit the upload rate by returning HTTP 429.
