Athletes who are still carbohydrate loading may want to watch this video when it is released. It describes the story of athletes who used a row boat to self-propel themselves from California to Hawaii running on a low-carb, high fat diet. They set a speed record for this! Of course their bodies were fat-adapted before they started.
I read The Lore of Running cover to cover a few years ago. It is often considered the “Bible” of running. The author, Professor Tim Noakes, is shown in the first Cereal Killers documentary, and in this trailer, ripping pages regarding carb loading out of his book. It makes a powerful message.
The movie will be published in March.
