Battle remembered in the long run? (8)
I believe the answer is:
This could be a double definition.
'battle remembered in' is the first definition.
'marathon' can be an answer for 'battle' (I've seen this before). I'm not sure about the 'remembered in' bit.
'the long run?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for marathon that I've seen before include "Long-distance running event", "Long run (with a wall to get through!)", "Footrace of 26 miles 385 yards", "Race of about 26 miles", "The longest foot race in sport".)
