Would say that nutrition is highly individual. and vital for an HIM, so good question! You\'ll find people using a whole range of different strategies for nutrition. The bottom line is - try it out, before the big day.
Rather than give you answers (of which there aren\'t many definites!), here\'s some questions to think about/ask people about/research for yourself:
1 - pre-, during-, and post-race nutrition serves different purposes. What are these, and what does that indicate about the sort of things you should be eating or drinking?
2 - what sort of drinks and food will be you personally be able to take in during races?
3 - how do you test point 2, ie how can you best replicate race-day conditions, without actually doing the distance?
4 - what\'s available on the course on the day? Will you use it?
