Carkeek Hydration and Nutrition

Talked with Bruce briefly about race nutrition. His recommendation was 200 calories an hour after the first hour. Preferably liquid. Liquid nutrition to avoid stomach upset and the fact that "Most people aren't going to eat 10 GUs if they can help it." He uses a powdered product (can't remember the name) and mixes it pretty concentrated in a secondary bottle, and drinks it with water from his water bottle. I haven't been training with liquid nutrition (when I do use fuel) so I'm not sure this is a completely viable option for Carkeek.

That was a lot less than I had been figuring on consuming, especially if you figure that I'll be moving pretty slowly and burning something between 200 - 300 calories a ~2 mile lap! ~400-600/hr). So I went back to look at my notes; and Hammer has the most solid recommendation and reminder (in their Fueling Handbook) about how much your body can normally absorb. Fluids: 17-28 oz/hr, Fuel: 240 - 280 calories/hr.

So if this is to be believed, then my standard marathon hydration/nutrition plan is the way to go. So a 22 oz bottle every hour, probably with nuun http://www.nuun.com/ just to be better safe than sorry. GUs (or equivalent) starting at 45 minute (normally ~5 miles), and every 25 after (~3 miles).

I'm having trouble believing that is going to be enough. I'd have to go dig it out, but I remember reading in 'The Lore of Running' that one of the better ultrarunners out there replaced ALL of his calories burned. I don't think I'd go that far, but I think I am going to try for closer around 300-400 calories an hour if my intestinal tract can handle it. It's going to be a great opportunity to experiment, so why not. I'll never be more than a mile from a portasan, and I'll be running in the woods. :)

I'm bringing along GUs, some Hammer Gel in flasks, and some CLIF nectar Organic Bars. The race is providing all sorts of other goodies, including "bananas, oranges, PBJ, grilled cheese, soup, potatoes, salt, Halloween candy, chips, energy bars (probably Clif), some gels, Nuun, Gatorade, water, Caffe Vita coffee". I'm wondering if I should make a batch of "Orange Stuff" (choolwhip/jello fruit salad). Hmmm.....
