Run to end of arena following car (6)
I believe the answer is:
afford
'run to' is the definition.
(thesaurus)
'end of arena following car' is the wordplay.
'end of' says to take the final letters.
'following' becomes 'f' (used when citing page numbers etc).
'car' becomes 'ford' (ford is a make of car).
The final letter of 'arena' is 'a'.
'a'+'f'+'ford'='AFFORD'
(Other definitions for afford that I've seen before include "Able to bear the expense" , "Be able to buy" , "Have the financial means" , "Provide; be able to pay for" , "Able to bear the cost of" .)
