There was a good talk organised by Ellen in February/March (I think) – the post about it is here:

It was very informative and gave exactly the sort of information you are talking about – I think the slides subsequently became available via Ellen and you may be able to get a copy. Beth, the presenter, was very experienced and went into a huge level of detail. She might be able to help you get your fuelling right for training and racing.
Cheers,
