Expression: "Go walking"

[Tom]

Hi

Please see below. If I am not mistaken, the red answer is incorrect because it does not answer how but answers where.

A- "How are you going?"
B- "I am going walking." VERSUS "I am going on foot."

A- "Where are you going?"
B- "I am going walking."

Hi Tom

A couple of comments.

A- "How are you going?"
B- "I am going walking." => You're right. This is wrong.
VERSUS
"I am going on foot." => It would be more natural to simply say "On foot."

A- "Where are you going?"
B- "I am going walking." => A more natural answer would be "For a walk."
