I like the taste of plaggy water bottle flavour water Although its not a strong tasting as a shot from them 70s water pistols(come on admit it,you've drank the water from one).
Food wise,pasta the night before a long morning ride(thats been a while since Ive done that,operation still looming)and I like the small packets of fruit and nut mix that Sainsbury's do.Couple of them in the saddle bag and Im sorted for a couple of hours
