*Regular one visiting clubs after. (8)

I believe the answer is:

periodic

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

'regular' is the definition.
(I've seen this in another clue)

I don't understand the rest of the clue.

(Other definitions for periodic that I've seen before include "Cyclical" , "Recurring at regular intervals" , "Intermittent" , "Occurring or appearing at intervals" , "Occasional" .)

I've seen this clue in the Sydney Morning Herald.
