I’m not sure if anyone has read the book Ultramarathon Man, or read anything about Dean Karnazes’s race day nutrition, below is a snipet of an interview that speaks to what he does for calories on his runs
From Interview:
3) When you run beyond 100 miles, what is your caloric “steady state”, ie, what is your average calorie burn per hour? And how many calories do you take in? What do you think is the most calories you have burned in one event?
DK: On these long runs, I’m what I call an “opportunistic eater,” meaning that I eat anything I can get my hand on that has lots of calories. Usually my diet is very strict: I don’t eat any refined sugar, I consume only good fats (i.e., mostly mono and poly unsaturated fats and omega-3’s, and eat no trans fat or hydrogenated oils), and avoid refined foods. However, on these long runs, I find it impossible to consume enough calories eating wholesome foods, there’s just too much fiber and bulk that fills me up without providing the necessary calories. So, on these longs runs I resort to highly refined foods and calorie dense items, like pizza and pie. During one 200-mile run we kept a food log, and I consumed 28,000 calories in 46 hours and 17 minutes of running. And I still lost five pounds!
I know the context of what he does is differant, but I was curious on thoughts on this concept of using calorie dense (and otherwise unhealthly) foods for long training sessions and appropriate applications (if any)…
