I like walking a lot - not hardcore trekking but a 7/8 hour walk over the kind of peat moors you get along the Pennines in northern England suits me fine. I have a border-collie dog - not sure if you can count having a dog as a hobby as such but she's a massive part of my life and walking seems a bit pointless when there's no hound scouting out the path ahead. Apart from walking and hounds, I'm really into comics/graphic novels (but not really superhero stuff,anything from Krazy Kat to Lost Girls via Joe Sacco and Love & Rockets), folk/traditional music, twiddling the handlebars of my moustache, amateur theatre, art/illustration with dip pen and gouache. The two things I don't do but must do before I die are sailing (just something like a dinghy or laser would be fine) and bee keeping.

EDIT - oh and I'm an armchair fan of many sports but especially football (soccer) and cricket.
