That actually sounds like it works out well!
Something I've never even thought of.. fueling up. What is Gu??
It's a gel like substance that is about the constancy of cake icing. Mainly a mix carbohydrates with some electrolytes added in. Packages approximate 100Kcal of energy.
They are used to help keep glycogen (sugar) levels in the blood stream up during long periods of exercise. The body only has enough glycogen in the system to allow 90 minutes of hard work. Once the levels get too low, the brain starts to kick in and say stop to the body since the brain can only burn glycogen as a fuel.
So in a long duration event or training period lasting more than 90 minutes, one would start to take in gels, or other carbs around 45 minutes in and then once every 30-60 minutes. Gels are one of the better choices since it is near liquid and the GI tact has a problem with solids once the body starts to work hard. Undoubtably, you will find many responses noting the yuck factor of gel. Before giving up, try a bunch of different brands and flavors.
