Something to be aware of. On the north coast you're riding through a lot of sheep shit. If it's rained it's going to spray everywhere, apart from making a right mess of your bike, if you get this on your bike bottle, you may have issues. If you can, use bike bottles that have a cover over the top so that it is protected, or find a way of carrying the bottle that is out of the spray.
Oh, and if you touch your tyres, wash your hands. Alcohol hand gel may be a good idea here.
