Low carb feeding on a marathon swim (and feeding in general)

I did a 2 mile ows last year and it was a gateway drug. It was beautiful and I felt so free once I got into a rhythm and realized I wasn't going to drown. This season, I have the opportunity to do a 10k and maybe even a 10 mile swim. I currently swim 11 miles a week and plan to increase that. One thing I'm concerned about on a longer swim is feeding. I currently eat low carb (50-60g a day, almost exclusively from fruits and veggies) because I like what it does for my brain, energy levels and waistline. I also like not getting pass-out hungry. I understand that this is heresy in the world of swimming, but I was wondering if there is anyone out there who does marathon swims low carb. What do you eat? Do you eat at all?

  • I've done several 10Ks on just water and I'm really slow, all were over 4 hours. The last one, I had a gel in my suit but never ate it. I also trained in the morning before breakfast, though I'm not on a low carb diet. Last year I converted to real food on my longer swims and I love it. Blended sweet potatoes, tart apricots and maple syrup is my favorite but I've tried a few others: PB&J sandwich quarters, applesauce with cooked oats. I'll continue to experiment next year when I start training again.
