Resent having to be incredibly rugged (8)

Ross

I believe the answer is:

begrudge

'resent' is the definition.
(synonyms)

'to be incredibly rugged' is the wordplay.
'incredibly' indicates anagramming the letters.
'rugged' is an anagram of 'grudge'.
'be'+'grudge'='BEGRUDGE'

'having' acts as a link.

(Other definitions for begrudge that I've seen before include "Envy, resent having to give" , "Envy, have feeling of resentment" , "Envy the pleasure of" , "Be resentful of" , "Envy, resent other's good fortune" .)

I've seen this clue in The Sun.
