Going in circles on a trail to Barking (10)

I believe the answer is:

rotational

'going' is the definition.
(thesaurus)

'in circles on a trail to barking' is the wordplay.
'in' is an insertion indicator.
'circles' is an anagram indicator.
'barking' indicates anagramming the letters (UK slang for mad).
'on'+'a'+'trail'='onatrail'
'onatrail' anagrammed gives 'rational'.
'to' is an anagram of 'ot'.
'rational' placed around 'ot' is 'ROTATIONAL'.

(Another definition for rotational that I've seen is " going round".)

I've seen this clue in The Independent.
