Anselm struggles to find race venue (2,4)
I believe the answer is:
le mans
'race venue' is the definition.
(as in 24 Hours of Le Mans)
'anselm struggles' is the wordplay.
'struggles' indicates anagramming the letters.
'anselm' is an anagram of 'LE MANS'.
'to find' is the link.
(Other definitions for le mans that I've seen before include "Place" , "French motor-race venue" , "French car racing track" , "French motor-racing track" , "French 24-hour motor race" .)
