Pacific group about to enter long-distance races (6,2,7)
I believe the answer is:
league of nations
'pacific group' is the definition.
(I've seen this before)
'about to enter long-distance races' is the wordplay.
I cannot really understand how this works, but
'about' could be 'on' and 'on' is located in the answer.
'long' could be 'l' and 'l' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for league of nations that I've seen before include "Old pacifists" , "Pacific group" , "international organisation" .)
