All rounders in track athletics? (4)
I believe the answer is:
laps
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for laps that I've seen before include "Drinks; circuits" , "Scoops up with the tongue" , "Circuits of a racetrack" , "Circuits of track" , "Pals doing rounds of the track" .)
