Map redone: rearranged walk (9)
I believe the answer is:
promenade
'walk' is the definition.
(I know that promenade is a more specific form of the action march)
'map redone rearranged' is the wordplay.
'rearranged' indicates an anagram.
'map'+'redone'='mapredone'
'mapredone' is an anagram of 'PROMENADE'.
(Other definitions for promenade that I've seen before include "Place for strolling by the sea" , "Esplanade" , "Seafront walk" , "Seafront walkway" , "Seaside walkway" .)
