Arduous journey (4)

Ross

I believe the answer is:

trek

'arduous journey' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for trek that I've seen before include "Long hike" , "Long hard journey on foot" , "A long arduous walk" , "Long walk in the mountains?" , "Long and difficult trip" .)

I've seen this clue in the LA Times, The Telegraph, The Wall Street Journal, the Newsday, the USA Today, The Guardian, the Universal, the King Feature Syndicate and The New York Times.
