I believe the answer is:

programme

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

'plan' is the definition.
(I know that plan can be written as programme)

'for golf hit endlessly' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'golf hit endlessly' becomes 'gramme' (I can't explain this - if you can you should give a lot more credence to this answer).
'pro'+'gramme'='PROGRAMME'

Can you help me to learn more?

(Other definitions for programme that I've seen before include "Menu of events" , "Radio or TV show" , "Schedule of events" , "List of events" , "Radio or television show" .)

I've seen this clue in The Telegraph.
