Following West Indian religion, runs a trek around capital of Trinidad (9)

I believe the answer is:

rastafari

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

'following west indian religion' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'runs a trek around capital of trinidad' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'trek' becomes 'safari' (I can't explain this - if you can you should give a lot more credence to this answer).
'around' is an insertion indicator.
'capital of' says to take the initial letters.
The first letter of 'trinidad' is 't'.
'safari' placed around 't' is 'stafari'.
'r'+'a'+'stafari'='RASTAFARI'

Can you help me to learn more?

(Other definitions for rastafari that I've seen before include "name of an Ethiopian prince" , "turned to old emperor" .)

I've seen this clue in The Independent.
