This is just guesswork, but if you're not eating a fairly strict low-carb diet I'd say the increase is due to the release of stored glucose and possibly the conversion of a certain amount of protein into glucose. The ratio of one reason to the other depends on how strict the diet is with regard to carbohydrate and protein. > 2.

What's her priority; athletic performance during the marathon or blood sugar control? If it's the former, follow the mainstream advice (carb junk and electrolite drinks). If it's the latter, stick to the normal (probably low-carb) diet and supplemental sodium and potassium if necessary. When actually on the road, if it were me, I'd go with jerky, cooked meat that isn't too lean, hard boiled eggs--that sort of thing-- protein and fat rather than carb junk. Something to keep in mind is that the ADA dietary recommendations are not low-carb. For that reason the mainstream advice for diabetic athletes isn't really any different than that given to non-diabetic athletes. I think it's ridiculous, but that's just me. > 3.

Since it's walking rather than running (the relative intensity is low), ones regular diet plus a little supplemental potassium and plenty of water should do it. There's at least one study that I know of that suggests fat is a better energy source for athletes than carbohydrate. I feel that's especially true for those who control their carbohydrate intake (where the body has at least partially shifted the emphasis from carbohydrate to fat as the preferred energy source). With that in mind, protein and fat rather than carbohydrate prior to and during the event make sense. --
Bill, We are not doing low carb so maybe that is it. I appreciate the reply.
