Be averse to getting into pedalo at headland (6)
I believe the answer is:
loathe
'be averse to' is the definition.
(to loathe something is to have an aversion to it)
'into pedalo at headland' is the wordplay.
'into' indicates a hidden word.
'LOATHE' is hidden in the letters of 'pedalo at headland'.
'getting' is the link.
(Other definitions for loathe that I've seen before include "Strongly detest" , "Abhor, execrate" , "Find disgusting" , "Find repugnant" , "Hate (someone)" .)
