At 55.5 yrs old, I am in good health, but not necessarily top physical shape. When I use google maps for a destination, I use the "walk expectation map" for my arrival time. I only use this when I have the occasional gig that I must appear for, not my busking. I normally beat that time by a long shot. It is useful to help release stress of hauling ass lol and allows for fixing flats, or what ever mayhem might come about including sightseeing and just walking. Hope helps someone .
