African running along behind American on the outside (7)
I believe the answer is:
angolan
'african' is the definition.
(Angolan is an example)
'running along behind american on the outside' is the wordplay.
'running' is an anagram indicator (the letters run around to different places).
'behind' says to put letters next to each other.
'on the outside' means to remove the middle letters.
'american' with its middle removed is 'an'.
'along' is an anagram of 'angol'.
'angol'+'an'='ANGOLAN'
(Other definitions for angolan that I've seen before include "Coming from a southwest African country" , "from Africa" , "One from Luanda" , "Eg, native of Luanda" .)
