On advice from my doctor I am going to take my own food to eat in Delhi prior to my competition to help eliminate the chances of getting the dreaded "Delhi Belly".
I approached Back Country Cuisine who make food "for adventurers" to see if they would be able to help me with freeze-dried meals. Although the food is aimed at the kind of adventurers who are climbing mountains and braving the great outdoors, they were keen to help me out on my heptathlon adventure at the Commonwealth Games!
So a big thank you to Back Country Cuisine for their support. For more info check out http://www.backcountrycuisine.co.nz/bcc/
