How to use activity recognition to detect walking / running against on_foot

Google Play Services Activity Recognition has

DetectedActivity.RUNNING,
DetectedActivity.WALKING,
DetectedActivity.ON_FOOT

when I get an activity update for walking or running, I get ON_FOOT

how can i differentiate?

I know this suggests that RUNNING and WALKING: "This is a sub-activity ON_FOOT"

Thank you for your help.
