How do energy gels for running work?

Answer 1

All the energy gels are is a easy to consume and digest gel that provides caloric energy. or in less scientific terms, its easy to eat while running food that gives you energy. As you run your body burns calories and thus to continue to have energy while running longer distances easy to consume/digest forms of energy can be beneficial. For the average runner 100 calories / 45 minutes or running can maintain your energy level which conveniently is the size most energy gel packets come in. However all they really come down to is a different form for food that is easier to consume while running, no real magic.
