Running warm up/down 1:00:00 
XC Zone's Tuesday night training.
Dave took us on this fairly gnarly warm-up run near the bottom of Penguin.
Then it was 6x800m loops at the base of Penguin which I think is as good a workout as anything one can do in town.
I have no idea, but anyone out there know if the bottom end of Penguin has been mapped as well as the terrain just north of downtown Old Chelsea?
