If you want to perform at your best as an endurance athlete, you need to stay on top of your protein intake. For years we’ve had pretty clear guidelines for what works best but a recent study has come out with the potential to completely reshape what we thought we knew.

Previously we believed that consuming more than 20 grams of protein in one sitting was redundant and that any excess would be wasted. Because of this nutrition guidelines were to spread protein intake evenly throughout the day which would optimise muscle protein synthesis. However, this new study challenges that foundational concept. 

What is the new research?

The study was a randomised control trial, widely considered the gold standard in research due to its controlled and double-blind setup. To achieve precise tracking, researchers gave cows isotope amino acid infusions which became incorporated into the milk proteins produced by those cows. Athletes were given different amounts of this traceable milk...

When it comes to athletic performance, nutrition plays a pivotal role. For athletes, particularly those engaged in high-intensity endurance sports like triathlons, understanding caloric needs is crucial. One common question that arises is whether 2000 calories per day is sufficient for a triathlete. In this blog post, we will delve into the factors that determine caloric needs and explore whether 2000 calories can adequately fuel an athlete's performance.

Understanding Caloric Needs

Basal Metabolic Rate (BMR)

The first step in determining caloric needs is understanding your Basal Metabolic Rate (BMR). BMR represents the number of calories your body requires at rest to maintain vital functions such as breathing, circulation and cell production. For most people, BMR accounts for about 60-70% of your total daily energy expenditure. There are various equations to estimate your BMR – we show our athletes which one is the best one for determining BMR in the Triathlon Nutrition...

In the world of triathlon, relentless training isn't enough—you need the right fuel to power you through not one, but three sports. The triathlete's diet is more than just food; it's a strategic plan that keeps your energy levels up, recovery fast and performance at its best. So let's break down the essentials of what goes into a triathlete’s diet, why it matters and how you can optimise your own nutrition for maximum results.

Why Nutrition is Key for Triathletes

Before we get into the nitty-gritty of a triathlete's diet, let's talk about why nutrition is so crucial for triathlon. Triathlons are not your average Sunday morning jog —they are a test of endurance and stamina, making nutrition a crucial piece of the performance puzzle.

Think of it this way: Would you drive your car across the country on an empty tank? Didn't think so. Your body needs fuel too, and not just any fuel. Premium grade.

A well-balanced triathlon diet ensures you've got the energy to power...

Triathlons are one of the most challenging (and awesome) multi-sport events, combining swimming, cycling, and running into a single race. Triathletes are dedicated individuals who love to train hard, often balancing training with work and family life. 

They train to test their limits, improve their health, and achieve personal goals. Becoming a triathlete requires a lot of commitment, but it's also incredibly rewarding.

I'm Taryn Richardson, the founder of Dietitian Approved and I’ve been working with triathletes for 15 years, helping them reach their performance goals through my Triathlon Nutrition Academy program. In this article, I'll share insights into what triathletes should eat to boost their performance, aid recovery, and stay hydrated during training and races.

What a Triathlete Eats for Performance

When it comes to triathlon training, nutrition plays a crucial role in providing the energy needed to endure long endurance sessions and high-intensity workouts....

Triathlon is an endurance sport that requires a significant amount of energy. It consists of three different disciplines: swimming, cycling, and running, all performed in immediate succession over various distances. As such, triathletes need to fuel their bodies appropriately to meet the high energy demands of their rigorous training and competition schedules. This brings us to the question - how many calories should a triathlete eat? In this blog post, we will delve into the world of triathlon nutrition and provide some insights into this important aspect.

Understanding Caloric Needs

The number of calories a triathlete needs can vary greatly depending on several factors including age, gender, weight, body composition, training volume and intensity, goals and medical history. However, as a rough guide, triathletes can require anywhere between 2,500 to 7,000 calories per day (10.4MJ – 29.2MJ). That's a huge range right?!

But there is no one size fits all with nutrition. And your...

As a triathlete that loves to push their body to the limit, maintaining a balanced intake of essential nutrients is vital. Unfortunately, nutrient deficiencies are a common problem that can significantly impact your training and racing performance. Sometimes without you even knowing there's a problem!

Ensure you're optimising these three nutrients in your diet as an endurance athlete if you want to train harder and race faster:

Key Nutrient Deficiencies in Triathletes

Iron

Iron deficiency is unfortunately prevalent among endurance athletes. It’s a critical component of haemoglobin, which plays a key role in transporting oxygen around the body from your lungs to the working muscles and other tissues. Iron deficiency can lead to anaemia, characterised by fatigue, tiredness, weakness and a noticeable decline in performance. Triathletes should aim to include iron-rich foods like lean meats, lentils and green leafy vegetables such as spinach in their diet. But...

Want to transform from flailing to fast and fluid in the water? Effortless Swimming coach Brenton Ford shares his insider view on frequent flaws undermining many triathletes’ swim potential.

As a leading technique guru analysing thousands of underwater videos, he’s honed an eagle eye for subtle things sabotaging speed and efficiency. 

Take note of these common trending mistakes:

Over Rotating

Instagram makes rolling almost 90 degrees tempting. But for efficient forward propulsion, most athletes benefit from a narrower 30-40 degree rotational range using core strength rather than momentum.

Excess drag from pivoting too far simply slows you down. It also stresses the rotator cuff and compromises arm position entering the water. Think "rock the boat" not "capsize the boat"!

Exaggerating Cues

Many triathletes overcook helpful coaching cues into performance-limiting extremes:

High elbow recovery becomes restrictive jamming the arm against the torso rather...

Proper fueling is essential for triathletes to get optimal performance during intense training and competitions. Some athletes, like Jody Walker, find themselves without an appetite, making it challenging to consume the necessary calories and nutrients. Jody joins me on the podcast for the third time today, to share her experience and the strategies she implements to overcome this hurdle.

Shifting to Lower Fiber Options:
 

Before joining the Triathlon Nutrition Academy, Jody’s diet was designed around naturopathic principles, and while she ate good food it wasn’t suitable for triathlon training. One big issue was her high fiber intake, which left her feeling full and made it difficult to consume sufficient carbohydrates for optimal training and recovery. To combat this, Jody shifted to lower-fiber options and adjusted her carbohydrate sources, helping her feel more comfortable and meet her energy needs.

Fueling your body without an appetite: 

To combat...

It was an absolute thrill to chat with journalist and author Christine Yu about her groundbreaking new book “Up to Speed: The Groundbreaking Science of Female Athletes”.

This epic 500+ page volume comprehensively synthesizes the latest science around optimising women’s health and performance in sport. The wide range of topics explored span physiology, hormones, nutrition, injury prevention, mental health, sexuality, sports equipment design, policy reform and much more.

As Christine dug into many hundreds of studies and interviews over 18 months of intensive research for the book, some clear and concerning themes emerged:

• We are only just beginning to unravel even basic functional knowledge around the intricacies of the female body and how sex differences impact all aspects of human performance and experience. Research specifically exploring female physiology and health remains largely underfunded compared to males.
• Outdated paternalistic attitudes have actively...
