Tell us about your weekend ride

This is £5 a day, all in. He actually came in under budget at the end.

He slept on people's floors and did a bit of wild camping in Scotland, and ate either really cheap supermarket food, food that was bought for him by the friends he saw along the way or cheap meals out. I bought him some cheese, nuts and salad and hid them in his panniers as I was worried he might get a vitamin deficiency. One meal consisted of 4 yumyums (4 for a pound! up north, of course) so I don't think I was wrong to worry.

Na, will never go that cheap on food then. Would go bread/cheese/salami route + fruit + minerals with a proper meal at least once a week.
As per accommodation, yeah, Couchsurfing and Warmshowers are your best friend along with some wild camping if you fancy (my gf doesn't as she's arachnophobic :-( )
