Coaches someone who puts effort in to cycle (8)
I believe the answer is:
trainers
'coaches someone who puts effort in to cycle' is the definition.
'trainers' can be an answer for 'coaches' (I've seen this before). I am not sure about the remainder of the definition.
'coaches someone who' is the wordplay.
'coaches' becomes 'train' (I've seen this before).
'someone who' becomes 'ers' (I can't justify this - if you can you should give a lot more credence to this answer).
'train'+'ers'='TRAINERS'
Can you help me to learn more?
(Other definitions for trainers that I've seen before include "People who coach athletes, or running shoes" , "Coaches: leisure footwear" , "needed to get the most out of racehorses?" , "Casual footwear" , "Casual shoes" .)
