Speedy type doing the rounds of paved surface (4)
I believe the answer is:
pace
'speedy type doing' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for pace that I've seen before include "politely expressing disagreement" , "With the leave of; speed" , "Gait" , "Tempo, rate of moving" , "speed of movement" .)
