Practicing your 'track' around it is key, and knowing when to roll and when to swing the hammer is important. Took me a few tries but the main points are the same.

Used the hammer to break the brick walls and piles of stone, the pillars and the big wagon thing.  Pretty much everything else can be broken with a roll, making things much faster.  I went south west immediately from the hammer, and then followed a clockwise motion to finish. 
 
Also, just as a heads up, you won't get first place if you get exactly 25 seconds.  It must be under.

I did exactly this!

Me too, works like a charm. Just had to keep on going until I nailed it.
