7 Day Triathlon Diet Plan

The key factor in triathlon training is nutrition. Eating a balanced diet can be complex sometimes but it doesn’t have to be. If you’re already eating well, that’s a plus factor. If you’re starting from scratch, no need to feel intimidated. It only takes a few adjustments to your eating habit which follow some simple guidelines.

To undergo training for the three main triathlon disciplines namely swimming, cycling and running, you need to have a diet plan. What do you want to achieve? Obviously, you want to attain your ideal weight, gain muscle, boost energy, manage stress and strengthen your cardiovascular system. So, design your meal plan based on your objectives and training regime.


Why Proper Diet Is Important To Athletes

A diet plan for triathlon training should be designed to build stamina and endurance. What foods should you eat? You want to have a low fat, rich in carbohydrates, proteins, vitamins and minerals diet regime.

Whole and organic foods are the best choices while staying away from processed and refined food products. Choose foods packed with vitamins such as vitamin C, vitamin A, vitamin D, vitamin E, vitamin B complex and minerals such as iron, sodium, calcium, potassium, magnesium, zinc, and phosphorus.

Your protein requirements can be supplied by lean meat such as chicken and turkey breast without skin, lean beef, lean veal, lean pork or lean lamb. You can also opt for fish and shellfish such as tuna, salmon, mussels, clams, halibut, tilapia, scallops, shrimp, Pollock and cod.

Proteins are the building blocks of bones, muscles, cartilage, skin, blood and are very important for the functions and structures of different organs and tissues of the body.

Main carbohydrate sources may come from barley, brown rice, buckwheat, millet, oats, corn or quinoa. Buy whole-wheat or 100% whole grain labeled pasta, pitas, tortilla and crackers.

Oatmeal can be a staple for breakfast but you can make a variety by trying dry cereals. Carbohydrates give fuel to the body and increase glycogen contents of the muscles to boost energy and vitality.

Vitamins and minerals can be taken from fruits, vegetables, nuts, seeds and dairy products. Berries, banana, avocado, leafy greens, carrots, red pepper, tomatoes, mushrooms, broccoli just to name a few are packed with nutrients to help repair cellular damage especially during training.

These essential nutrients also break down food into energy, bolster immune system, keep bone and tissues healthy, and play very important roles in the general metabolism of the body.

With all this in mind, it’s time to show you a meal plan that will set you up for success.

Hey everyone, I’m Sandra Ryan and I’ve been contributing to this website for almost a year now.

My professional background is in finance where I work at a small bank outside Austin, TX, as an accounting technician. I’m still gradually working towards becoming an accountant by attending night classes, but my real passion is sport.

I’ve been involved in martial arts since I was about 8 years old when I had to figure out ways to outdo my 3 older brothers who were in constant WWE style fights. Nothing ever happened more than bruises and the occasional cut, but once I started Taekwondo I just couldn’t get enough.

I have won many state championships over the years, but have started to take a bit of step back from competitive fighting. Mainly down to a few leg strain injuries that basically mean that I cannot perform at my absolute best anymore.

My hunger for competition has been replaced by running marathons and in the past 2 years also competing in triathlons. So far I have completed 7 marathons and 2 triathlons and my aim is to complete an Ironman in the next couple of years.

When the opportunity came up to contribute to a website with training tips I immediately loved the idea. You’ll see a lot of my blog posts on triathlon training, and if you have questions, just leave some comments.

We will be happy to hear your thoughts
