How to Study Your Long Distance Nutrition

Your long distance nutrition should give you an even amount of energy throughout your entire workout.  You can tell if it's working by reviewing your heart rate profile.  If it is nice and even, then you are on track.  If it is not, then you have some work to do.

A great way to fix your nutrition is to measure it out so that you take it evenly over long periods of time.  Bring along extra fuel in case you are underfueled.  

Proper fueling for long workouts gives you a huge benefit - you get much more quality out of the time spent and don't need as much quantity, reducing fatigue and risk of injury.
