Doctor Zhivago heroine in spectacular arena (4)

I believe the answer is:

lara

'doctor zhivago heroine' is the definition.
(I've seen this in another clue)

'in spectacular arena' is the wordplay.
'in' indicates a hidden word.
'LARA' can be found hidden inside 'spectacular arena'.

(Another definition for lara that I've seen is " Dr Zhivago's lover".)

I've seen this clue in The Guardian.
