Running

any ideas on nutrition for long distance cycling-or basically same as running?

I don't know if this is any help but this is my ironman nutrition plan (note that this isn't some carefully calculated balance of carb and calorie intake based on weight and effort, this is just me muddling through with what appears to work):

Breakfast: Bowel of Muesli with dried fruit, bread rolls with jam& butter, Coffee.
Pre race: Energy drink/electrolyte drink as an when I feel like it, energy gel 15-20mins before the swim.
Swim: nothing (obviously)
Bike: Couple of slugs of energy drink every 15 minutes (they provide drinks on the course so it is easy to top up), 1 energy gel every 30 minutes (i carry these decanted into a bottle on my dt). I sip water as and when I feel it's needed and if my stomach starts rejecting the energy drink. If for whatever reason I feel like I'm going to be under fueled I pick up solid energy bars on the course as and when I feel the need.
Run: Sip of energy drink chased with a sip of water at every aid station (little and often, the remaining water goes over my head) and an energy gel at approximately 10k, 20k, 27k and 35k. No solids on the run.

This seems to work for me and almost certainly wouldn't work for everyone. My intake on the bike is also waaay more than I would expect no need if I was doing just a cycle. So, I guess the simple answer is the one that has already been given by knightlancer - you can basically eat whatever you want (try it in training and see how you go). On 6-7hour rides I usually take 2x750ml bottles of energy drink and stuff my pockets with Nutrigrain elevenses, if I stop at a shop I might grab a sandwich and stash a packet of hobnobs in my pocket.
