What kit will you be wearing Rich?
I'll be wearing a Here Come the Belgians top.

What drink & fuel ( gels/bars/etc) would you take?
I've never had support before, and have got away with a 750ml bottle, and a few gels/bananas. Just make sure you've had a proper breakfast.

What spares?
Yep, 2 tubes, 2 gas, 2 levers, chain link & breaker, small multi-tool.

I've wrapped a tube round each Co2 cylinder, put the stuff in your pockets, it's to hand there, you don't want the faff of a saddle bag.
