What and when to have breakfast before Xterra

No one answered this?  With only 2 weeks to go - you probably don't want to eat anything you don't normally eat for breakfast.   I suggest you eat a normal breakfast and then go for longish run.  That should be enough to tell you if your breakfast choice is no good.

I usually eat cold cereal and skim milk.  Before my first Xterra, I rented a cabin at the venue, and ate in their cafeteria.  They had scrambled eggs  and bagels for breakfast.  I was worried that would kill my stomach, but actually, I never felt better!
