How walks up Kilimanjaro and fun runs are backed, or by whom? (7)
I believe the answer is:
sponsor
'how walks up kilimanjaro and fun runs are backed' is the definition.
I can't tell whether this defines the answer.
'or by whom?' is the wordplay.
I cannot quite understand how this works, but
'or' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sponsor that I've seen before include "advertising?" , "One financially supporting event" , "Back financially" , "Patron or backer" , "Patron or godparent" .)
