I mean even without knowing the area if you are hiking (which implies you are walking) 3.7 miles in 16 m then you are the apex predator of the world my friend. That's 20/25 km/h
(Yep. If you then tell it hiking is walking it gives you a reasonable response. It used to give you weird combinations of trails in the general area even when you tried to correct it. Now, with Google Maps info, it was confused about the mode of transit but if you cleared that up, it was correct.)
