There are two ways to use the plugin:
Create a custom field in your post called “runkeeper” and paste the “Share” url from the Runkeeper activity you want to feature.
Use the shortcode [runkeeper url=”example”] replacing “example” with the “Share” url.
The map and stats for that activity will now appear in the post in an iframe.
If the formatting isn’t quite right you can amend the size and offset of the Runkeeper preview in the Settings page.
