This position with target square b7 requires 152 moves.

The position is an adaptation of Rewan Demontay's adaptation of Branko Koludrovic, Cornel Pacura & Arno Tüngler's problem, using also a black pawn on h8 as suggested by Retudin. I have only added a black pawn on a8 and changed the white king's target square from h2.
