Ok, I'm really quite excited now . . .

I googled my problem and it appears I could be deficient in almost anything from vitamins B12 or D to copper to iron to carbohydrates to water??.  The cure could be . . .

more water,
less water,
jelly babies,
jelly beans or mints,
a salty snack or sugar,
gels, gu's or chump bars!!,
Cereal, porridge or toast one hour or possibly two hours before I run,
or even . . . an omelette!

Give me strength!

I decided to ask my very own experts at work, Hayley ran the marathon last year, Lucy is running this years with her husband for the Animal Health Trust.  They are both runners, not just people like me who thought it would be a good idea, bit of a laugh!.  I'm glad I did because they have come up with some great idea's, the consensus of opinion seems to be that I need to drastically increase my intake of food the 24 to 48 hours before a long run.  I have also now purchased a box of 'isogels' which I have a huge amount of faith in, maybe this is where the extra miles are coming from?

For now I'm trying to find something to eat every hour or so and will continue to do so tomorrow, then I shall 'roll' myself out onto the road, load up with the isogels and attempt . . . for the third time to run a whole, uninterrupted, 16 miles.
