Running event in hotel, working to support revolutionary leader (8)
I believe the answer is:
marathon
'running event' is the definition.
'marathon' can be an answer for 'event' (marathon is a kind of event). I'm not certain of the 'running' bit.
'hotel working to support revolutionary leader' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet).
'working' becomes 'on' (on can mean working or activated).
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'revolutionary leader' becomes 'marat' (I've seen this before).
'h'+'on'='hon'
'hon' after 'marat' is 'MARATHON'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for marathon that I've seen before include "Long-distance running event" , "Roman hat (anag) - race" , "Long distance race" , "Footrace of approx 26 miles" , "Severe test of endurance" .)
