I'm a little stuck... Click here to teach me more about this clue!

'trip runners' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'poorer at running through french city' is the wordplay.
'running' is an anagram indicator (the letters run around to different places).
'through' indicates putting letters inside (inserted letters go through the word).
'french city' becomes 'tours' (I've seen this in another clue).
'poorer'+'at'='poorerat'
'poorerat' anagrammed gives 'operator'.
'operator' going into 'tours' is 'TOUR OPERATORS'.
