Somebody once said to me "try to eat a rainbow" that's what i do. (Skittles excluded obvs).
Up to 50miles, just normal diet of fruit/muesli for breakfast, with home made flapjack for a snack if i stop.
Longer then I take banana, apple, cheese sandwich nothing special!
Recovery from a bigger ride is lots of water and normally grilled chicken and a huge heap of greens.....which is pretty much what I eat anyway.
Like many my carb intake is much lower the last 10 years, i find i just dont need them as much, ad I'm not needing to fuel as much as im hardly pushing the training envelope or racing any longer.
I do like a pint half way round any ride however..

but that's a purely physiological gain from my perspective....it a journey to somewhere, as i hate circular rides with no purpose!
