Riders from celebrity on vacation: see notes (8)
I believe the answer is:
cyclists
'riders' is the definition.
(cyclist is a kind of rider)
'celebrity on vacation see notes' is the wordplay.
'on vacation' suggests removing the centre.
'see' becomes 'c' (the word for the letter, according to Chambers).
'notes' becomes 'lists' (**).
'celebrity' with its middle taken out is 'cy'.
'cy'+'c'+'lists'='CYCLISTS'
'from' is the link.
(Other definitions for cyclists that I've seen before include "Pedallers" , "Bike riders" .)
