Round headland, see running fugitive (7)
I believe the answer is:
escapee
'fugitive' is the definition.
(escapee is a kind of fugitive)
'round headland see running' is the wordplay.
'round' is an insertion indicator.
'headland' becomes 'cape' (I've seen this before).
'running' indicates an anagram.
'see' with letters rearranged gives 'ese'.
'cape' placed within 'ese' is 'ESCAPEE'.
(Other definitions for escapee that I've seen before include "One getting away" , "One running from prison" , "Absconder, fugitive" , "One who's broken out of confinement" , "Fugitive from prison" .)
