Vinny's Allotment Plot

I would close off the ends of alternate pairs to make U shaped beds, like the floor plan of a GH.

The downside of that would be that your beds would basically become twice the length and you would have a lot of walking to do to get around them?
I was thinking more of a narrow path running down each side of the plot about 300mm in from the boundary allowing space for the half standard soft fruit I have growing there.
