Radio National covered university sprint (3)
I believe the answer is:
run
'sprint' is the definition.
(I know this)
'radio national covered university' is the wordplay.
'radio national' becomes 'rn' (this might be a standard abbreviation which I don't know about).
'covered' indicates putting letters inside.
'university' becomes 'u' (abbreviation for university).
'rn' placed around 'u' is 'RUN'.
Can you help me to learn more?
(Other definitions for run that I've seen before include "Take flight" , "Race, enclosure" , "Drive" , "Move fast or manage" , "string of performances" .)
