The Hogwarts Running Club is a virtual race club where you run races based on the honor system. I'll be doing my first event, the Unmasked 10 Mile 'Run for Your Life', although I'll be mostly walking it due to my darn knee issues D:
I'm 100% a Hufflepuff and drew something for the Hufflepuff Common Room group on Facebook XD

(and if you're not a member of the group but a HP fan, what's your house?)
