I thought you might find this guy interesting.

I want to add I am not saying you should be zero carb, I could never do that. But, it is interesting to see that someone CAN be zero carb and an endurance athlete. Not only that, but he doesn't have the emaciated look of many endurance athletes, he is actually fairly muscular. "

I wanted to quote what I said because it seems that you may have missed that part. I don't remember saying it was scientific at all, I just thought the OP might find it interesting. I did also say that I would not do zero carb, but I thought it was cool that someone could do it and run marathons.

To assume that my statement was suggesting the OP actually go zero carb was, well just that an assumption. I would NEVER tell someone to go zero carb. But, I think most people would agree that it is interesting to see people that can exert themselves to that level by doing exactly what so many people find to be impossible.

From the article you provided, here is probably the reason WHY he is able to do so:
"Runners with large aerobic capacities and relatively large leg muscles can store enough liver and muscle glycogen to fuel marathon runs at elite-athlete paces (paces approaching those required to challenge the current world records of 2:03:59 for men and 2:15:25 for women) without exhausting physiologic carbohydrate stores; runners with smaller aerobic capacities or relatively small leg muscles must run at slower paces or refuel during the race in order to avoid ‘hitting the wall.’"

Charles Washington has large leg muscles, especially for a distance runner.

Using the rest of the research paper to answer the OP question would be, yes you can carb cycle as a distance runner. You would carb load as usual before the race, and then probably need to 're-carb during the race, which many marathon runners need to do anyway, unless they have a very large lung capacity, a huge amount of stored glycogen and large leg muscles that make up over 7% of their body mass.

A blog is not considered a source of scientific research or valid evidence. To suggest that Zero carbohydrtes and endurance athletic training is approriate is MISINFORMATION. TO get the facts I suggest you purchase or check out from your local library:
Food Guide For Marathoners
Sports Nutrition Guidebook
Both are written by Nancy Clark a Registered Dietitian and a TRUE EXPERT in this area.

If you want to see scientific research on the importance of carbs when running...look here:

There are a lot of misconceptions about low carb diets, and even the information you posted is not right. I eat less than 30% carbs everyday. I don't have fatigue or other issues, actually quite the opposite. I am frequently told i am 'too happy' and have 'too much energy' and that I 'make people tired' by them watching me at work, etc.

I am not running a marathon to lose weight. I've been running a few marathons a year for awhile. I train for one race after another. I am just trying to lose a few pounds and lose some time from my pace while training. I belong to a spark team of marathoners, a few members use carb cycling. For someone my weight a low carb day would be 65 g and a high carb day would be 230g. It doesn't sound like an insane Atkins thing. If this isn't plausible, is there a way to lose weight while training? Remember, I've been running for years, and keep make PRs at my races. I looking to drop less then 10 pounds. Thx

I think carb cycling would be very difficult if you are training for a marathon, since that is the main nutrient required for high endurance. A lot of articles on running in magazines and in blogs have reported that most people trainig for a marathon actually gain a little weight. It requires too much fuel for all that intense training.

Carb Cycling as described in the information you shared does not have research to support it as a weight loss tool or beneficial when marathon training.

while one may be able to lose a few pounds while training for a marathon in the beginning stages, it is practically IMPOSSIBLE to lose weight as the training needs become more intense as the race date gets closer.

I am going to cut and paste one of the explainations, I found on a website. I've been running marathons for awhile and always thought carb restricting would be taboo. I'd like to drop a some pounds and get faster.
Here's the paste
Carb cycling is a powerful tool for weight loss. Combining the benefits of a low carb diet plan with periodic days of carb loading is one of the most effective ways to lose weight and keep it off. To most weight loss beginners, carb cycling seems too complex and confusing. Here is a simple plan that will give you all the weight loss advantages carb cycling can offer.

Why Low Carb?

Low carb is defined as a diet that contains 30% or less of carbohydrates. If you are trying to lose weight, eating a low carb diet will make a calorie restriction much more achievable because you will have more stable blood sugar levels and reduced hunger.

The main drawback of eating low carb on an permanent basis is fatigue, brain fog, loss of training performance and the inevitable carb cravings. The solution to this is the a carb cycling method.

Isn't Carb Cycling Just for Hardcore Bodybuilders?

meat - good for your waistline The carb cycling technique is used by bodybuilders who do take the concept to its extremes, but normal folk can utilize the same principals with a more moderate approach and still see the fat melt away while having 2 days of higher calories/carbs per week

I'm not familiar with carb cycling. Can you explain?

Is carb cycling plausible for a marathoner?
