Walked around Dorset (6)
I believe the answer is:
strode
'walked' is the definition.
(I've seen this before)
'around dorset' is the wordplay.
'around' indicates anagramming the letters.
'dorset' is an anagram of 'STRODE'.
(Other definitions for strode that I've seen before include "went on foot" , "Paced" , "Walked fast with long steps" , "Galumphed" .)
