Fell race (4)
I believe the answer is:
pelt
This clue could be a double definition.
'fell' is the first definition.
(I've seen this before)
'race' is the second definition.
The answer and definition can be both related to competing as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for pelt that I've seen before include "Hide; rain" , "Pour; hide" , "Hairy coat of a mammal" , "Run fast - rain hard" , "Subject to bombardment" .)
