I have a very stable routine for my long runs, which work well for me. But now I wonder if I need to switch it up a bit. Normally I stick to chocolate Gu gels and orange flavored Gatorade, and it works just fine. But I've been reading up on high fructose corn syrup, which is in both products.
Recently I learned about Hammer Nutrition and I'm wondering if I should switch. From what I've tasted so far, it is a lot more palatable, particularly the Orange-Vanilla flavored Perpeteum. It doesn't leave that nasty film in my mouth, which I suspect causes me to ingest more water than I should during the runs. But it does make me feel my head (I don't know how to actually explain the feeling other than that).
I recall about mile 19 last year when I got really light-headed, and I'm wondering if that's from either drinking way too much water (I think I stopped at almost every station), or if it's from the electrolytes situation. I had Chris pass me salty pretzels at that point, which helped my stomach, but this time around I am totally on my own. So even though it's a flatter course, it will be psychologically more difficult.
Anyway, back to the issue at hand. Does anyone know the difference between the Perpeteum and Sustained Energy? From what I can tell the Sustained Energy has more minerals, but that's about it.
