Forwarded to me for adding to this forum
I've realised over the past few years that maintaining my electrolyte levels on long days is extremely important or I feel very tired and get cramps. I use either of 2 ways to do this; 1) Eat salted nuts during the day (usually mixed salted nuts or cashews), or 2) add Gatorade to my water. Both seem to work fine, although on really long days (12+ hrs) I often use both. Then on arrival back at camp I am usually dehydrated and I find the best way to rehydrate is to make bouillon. I add 1 cube to 1L hot water and drink this. Sometimes I'll have 2 servings of this if I'm really dehydrated, and I also add a tablespoon of butter if I have any to make it taste better and help start to recharge my energy. eg. for the Becky-Chouinard route in the Bugaboos (17hr round trip) I had about 1-1.5L water/tea before I left camp, then 1L of water and 1L Gatorade on route + salted nuts, then 2-3L bouillon when I got back to camp. I find bouillon cubes are better than soup because they contain more salt and are way smaller and lighter.
