T-4 days-Food & Drink

Runners world say:

'Plan your week's eating with a variety of high-carbohydrate meals. Don't undereat, but take care to avoid junk food.
Do everything you can to avoid catching coughs and colds this week. Pack plenty of immune-boosting vitamin-C-rich foods like oranges and broccoli into your diet. If in doubt, take a daily 1000mg vitamin C tablet, and consider a multivitamin supplement.
Avoid the practice of preceding a carbo-loading period with a few days of carbohydrate starvation.'

I like the part about avoiding catching coughs and cold. To late! :(
I'm off to get some vitamin C though.
