Manage to find time to run (5)
I believe the answer is:
trace
'manage to find' is the definition.
(I've seen this before)
'time to run' is the wordplay.
'time' becomes 't'.
'to run' becomes 'race' ('race' can be a synonym of 'run'**).
't'+'race'='TRACE'
(Other definitions for trace that I've seen before include "Copy by drawing on translucent paper" , "Copy; describe; draw" , "Locate by investigation" , "Make a copy using transparent paper" , "Skimpy garment" .)
