TR - that site has your name all over it!! 
I'm an early morning runner. 16m+ and I will have coffee and porridge or readybrek - I can have this as I'm going out the door and don't seem to have to let it settle. Anything less is normally just coffee. If I feel I haven't eaten enough the day before I will have a bowl of porridge before going to bed.
But, this may all be about to change. I'm off work ill (second day) so putting my bed time to good use and reading Racing Weight with a view of reaching my optimal weight by VLM. 
Keir - put the coffee in a flask?
I'm also scheduling a some reading on long runs. I know of a few people recently, myself included, who have run a marathon pb, or close to, with minimal long runs. I'm wondering if the more experienced one gets at long distance running the less important the amount of long run training runs become.
