Super helpful thanks everyone.

Planning on 2xbottles and carrying a bladder to refill/purify on the go.
Will use energy sachets in bottles for extra carb, on top of flapjacks, bananas and gels. Emergency stash of salted nuts and skittles!

If I can get a coffee and cake I'll be well chuffed

Hi all, I'm riding this weekend (1st timer for BB200). Interested to hear how your water and food strategy worked out for you.
