Motoring event (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
rally
'motoring event' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rally that I've seen before include "Muster" , "Recuperate in gathering" , "Recover; car race" , "Get-together" , "recovery" .)
