The Race Eve pasta dinner: Is pre-race carb loading a good idea?

I may or may not have touched on the folly of carb loading, that your diet and glycogen stores are a body of work, and not something you can fix in the 48 hours before your race (though your glycogen stores and physical condition are certainly something you can break in the preceding 48 hours).

Still, the Race Eve Pasta Gorge is a favorite runner ritual, and while you may not substantially improve your glycogen reserves, you at least won’t go to bed hungry.

But instead of waiting a bit for the meal to digest, I immediately crossed the street onto the LUC campus and took off for Lincoln Park.

I bring this up because, while I didn’t feel sick running with such a disgusting meal in my stomach… the inevitable gas you’d expect from your stomach led to a realization.

On how the body uses energy during a race, why runners hit the wall in a marathon, and what can be done about it

A key fundamental issue with the marathon is that the distance is farther than the human body can capably race in one go without consuming fuel during the race.

Long story short, aka I’m about to paraphrase a ton of science without citing any sources:
