When to be fighting fit (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
bout
'fit' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bout that I've seen before include "Contest; illness episode" , "Wrestling contest" , "Attack (of illness)" , "Spell of eg drinking" , "wrestling match" .)
