One of the most challenging aspects of open water swimming is nutrition.
I have been battling with it since I started swimming long distance.
In any endurance activities, nutrition is essential because it directly affects performance but it is very difficult to find food that is easily digested.
Swimming adds another level of difficulty because there is no gravity and food is not naturally moving down, it stays longer in the stomach.
I found out throughout the years that I cannot eat any “engineered” food that packs a lot of calories in a very small volume. My body rejects it, yes I have to say it, I throw up. I can only eat natural salty food. I also have to have enough fluids. So, after many trial and error or I should say, nausea and throw ups, I found out that soup works the best for me. Plus I get a lot of pleasure ingesting something hot when I swim in cold waters.
I have been very fortunate to find the right type of organic and nonperishable soup; LYOFOOD makes freeze-dried soup, we just add hot water to it and I am good to go. I eat some bread as well to supplement it with some solid food. We are all very fortunate that Yoav is a great backer and makes fresh bread for all of us every day. During my 8 hours of swimming, I eat about 8 slices of bread, about 1 litter of thick soup, and some water. I am always experimenting with food when I swim, I am tempted to include some cheese those days!
