Timing is everything

Other than just getting daily nutrition requirements, it is important also to eat the right food and also ensure that you eat it at the right time. This will go a long way in ensuring that you maintain energy for maximum post-run recovery and when running.

When you are running, your body gets its fuel from fat sources and glycogen. Therefore, to increase the glycogen storage, and thus add fuel to your body, you need to increase your daily intake of carbohydrates. As you start running, your glycogen storage starts to get depleted. The more you continue to run, the more your glycogen reserves get depleted. Eventually, it will need to be replenished otherwise it can run out.

When your glycogen reserves get completely depleted, the body starts to burn fats. Therefore, to maintain adequate glycogen, you need to ensure that you eat before, during as well as after the run.

Before a running session

Before you start running, it is advisable to eat light snacks. These include things like wheat bagel and snack and it should be consumed roughly one hour before you start running. Make sure that whatever you have decided to eat, it should be something that your body can easily digest.

You should experiment with various foods to determine the foods that work best for you. While it is best to eat just before a run in order to maintain glycogen reserves, you need to understand that different people digest foods differently. Therefore, test some foods to see how you fare with them before shorter runs. After that, you can try something new prior to going out for a longer run.

During the run

It is important that you eat snacks as you run. This is more so when covering distances of 10-20 miles and more. This helps replenish what your body burns and at the same time provides you with more energy. Anything you eat in the course of the running ought to be quickly and easily digestible. These include things like fruits and energy gel. You may want to consider eating energy bars because they are small, light and also easy to carry as you run, not to mention that they are packed with complex carbs. Experts recommend that you take one energy bar after every 30-45 minutes.

But how can you carry snacks and run at the same time? Lately, manufacturers of running gears having been making things a little easier for athletes by producing certain belts or fanny packs which are specifically meant to carry nutritious snacks and fluids to be consumed when running. Use them to carry enough snacks to keep you fueled up during your long runs.

After the run

After you have completed running, your body is literally begging for restocking. Mostly, it begs for more carbohydrates which it needs to store as glycogen. Also, it needs proteins to help the muscles in recovering. Since the human body cannot possible understand when they do not get what they want, you could be made to pay dearly if you overlook these needs. This is why it is very important that 30 minutes after each running session, make sure that you eat proteins and carbohydrates. These not only help your body to recover but also make it strong for the next phase of running.

Training and running for a half marathon can heap a lot of nutritional demand on your body. It is important that you know the foods you need to eat before, during and after you have finished running. This ensures that your body has recovered well even after grueling sessions of running.
