Quickly train to manoeuvre on the rink (2,1,5)
I believe the answer is:
in a trice
'quickly' is the definition.
(I've seen this before)
'train to manoeuvre on the rink' is the wordplay.
'to manoeuvre' indicates anagramming the letters.
'on' is an insertion indicator.
'the rink' becomes 'ice' (ice is a kind of rink).
'train' with letters rearranged gives 'natri'.
'natri' put inside 'ice' is 'IN A TRICE'.
(Other definitions for in a trice that I've seen before include "quickly" , "Pronto" .)
