When running long distances, you have to consume a certain amount of water and a certain amount of gu. One of the problems that I come across is that when I am on long distances that my pace amounts in a large amount of gu: Caffeine, sugar and electrolytes and water in my stomach. My last few long runs have left me feeling less than stellar. I have so much of this in my stomach that I feel like I am going to throw up.
Does this happen to anyone else? How can you fix it?
