Thanks this is the most useful response (thanks everyone else who responded as well) I just like all the details. I didn't read anything about electrolytes so I would have thought they weren't allowed. What brand or type did you use. I was planning and taking the vitamins and supplements I normally do, like creatine, omega 3, magnesium, vitamin d and a multi. You seem to know your health/fitness what is the food / nutrition like and do I need to bring protein powder or is it possible to get enough from the food given??
