Wild parties lead to long walk (7)
I believe the answer is:
traipse
'long walk' is the definition.
(I've seen this before)
'wild parties' is the wordplay.
'wild' indicates an anagram.
'parties' with letters rearranged gives 'TRAIPSE'.
'lead to' acts as a link.
(Other definitions for traipse that I've seen before include "Tedious walk" , "Trudge or tramp in parties" , "Walk heavily" , "make slow progress" , "Pirates (anag) -- walk without 9" .)
