Do I have to make more than one bracha on my water bottle while walking to work?💧

I take a water bottle with me as I walk to work or to school and I drink it along the way do I have to make a new broa do I make one broa does it cover me the whole way to school how does it work when I keep changing locations with my BR on my water bottle so there is a concept called Travelers and the by a traveler is if he makes a while he's traveling the travels along with him the explain since the braa was not set on any specific location there is no change of location over here the BR was said as he was traveling so therefore the BR travels with him on his way to school if he said the BR though while he was at home then when he travels out of the house that would be a change of location R Feinstein though says if a person says the BR right as he's about to leave you know he says the next thing he does is he goes out the door he's already considered a he's already considered a traveler at that point and then the br will follow with him all the way to school
