When does a walk become a hike?
Generally, a “hike” suggests both longer distances and rougher (or at least unpaved) terrain than a “walk”. But there’s no definitive distinction. (Also, terminology varies in different parts of the world. For example, in New Zealand they go “tramping.”)
Since there’s no clear delineation between walking and hiking, it’s reasonable to suggest that a journey can include some of both, making it a walk/hike or a “wike.”
