How Do You Slim Down for a Triathlon?

Dec 15, 2022

Triathlons are a great way to challenge yourself and push your body to its limits. But if you’re looking to slim down for a triathlon, it’s important to understand the right approach to take. Here are some tips to help you slim down and get in shape for your next triathlon.


Create a Training Plan

Creating a training plan is essential for anyone looking to slim down for a triathlon. You’ll need to plan out your workouts, including the type of exercise you’ll do, the intensity, and the duration. This will help you stay on track and make sure you’re getting the most out of your workouts.

It’s also important to make sure you’re getting enough rest. Rest is essential for recovery, so make sure you’re taking at least one day off a week to rest and recover.

If you need help finding a good coach or training program to help you reach your goals, get in touch and we can provide some recommendations.


Focus on Nutrition

Nutrition is key when it comes to slimming down for a triathlon. You’ll need to make sure you’re eating the right foods in the right amounts and at the right time. Focus on eating lean proteins, complex carbohydrates, and healthy fats. Avoid processed foods and sugary snacks.

It’s also important to stay hydrated. Make sure you’re drinking plenty of water throughout the day. This will help keep your body functioning properly and help you stay energised during your workouts.

We are big believers in nutrition for performance and long term health. If you need help in this department, the Triathlon Nutrition Academy is your one stop shop to support training and racing.


Incorporate Interval Training

Interval training is a great way to slim down for a triathlon. This type of training involves alternating between high-intensity and low-intensity exercises. This helps to maximize your calorie burn and get your heart rate up.

Interval training can be done with any type of exercise. For example, you can do sprints on a treadmill or bike, or you can do bodyweight exercises like burpees and mountain climbers.

It’s an efficient use of your time and is great for managing blood sugar levels to. If you have a coach or training program, chances are you are already incorporating this style of training. 


Get Enough Sleep

Getting enough sleep is essential for anyone looking to slim down for a triathlon. Sleep helps your body recover and repair itself, so make sure you’re getting at least 7-9 hours of sleep a night.

It’s also important to make sure you’re getting quality sleep. Avoid screens before bed and create a relaxing bedtime routine to help you fall asleep faster and stay asleep longer.

If you are someone that typically craves sweets after lunch to get you through the afternoon slump, this may be an indicator you need more or better quality sleep.



Slimming down for a triathlon can be a challenge, but with the right approach, it’s possible. Start by creating a training plan and focus on eating the right foods to maximise your performance. Incorporate interval training into your workouts and make sure you’re getting enough sleep. With these tips, you’ll be well on your way to slimming down and getting in shape for your next triathlon.
