Championship season is on the horizon, and however your year has gone up to this point, the way you fuel yourself over the coming weeks can still make a real difference to how you perform, recover, and hold your form when it matters most.

I want to walk through the key nutrition principles I use with the GAA athletes I work with heading into championship, along with how to apply them specifically around match week.

1. Match Your Energy Supply to Your Energy Demands

This is the foundation everything else sits on top of.

Underfuelling relative to your training and match load leads to a drop in both performance and recovery.

Overfuelling, on the other hand, leads to excess body fat, since any energy your body doesn't need for training and everyday life gets stored away.

The goal isn't to swing towards either extreme, it's to find the sweet spot where you're taking in enough to perform and recover well, without it costing you unwanted body fat.

2. Bias Your Intake Towards Carbohydrates

When you eat carbohydrate-containing foods, they're broken down into glucose, and if not used immediately, stored as glycogen in your muscles and liver.

This glycogen is then the predominant fuel source used during high-intensity activity like GAA training and matches.

The amount of glycogen you've got stored heading into game-day is one of the major determinants of how much energy you'll actually have available to you during that game, which is why biasing your intake towards carbohydrates on an ongoing basis matters so much for a field sport athlete.

3. Get Sufficient Protein

Protein provides the building blocks for your body tissues, things like your muscle and joint tissue.

Without adequate protein, you won't get the full benefit of the training you're putting in, and you'll likely find yourself showing up to sessions still sore and stiff from the one before.

Aiming for around 2g of protein per kg of bodyweight, spread across your main meals, is a simple and effective target for most GAA athletes.

4. Don't Fear Fat

Fat has had a rocky reputation over the years, but it's essential, it's needed for hormone production, the structure of your cells, and the absorption of certain vitamins.

My advice is to bias your fat intake towards mostly unsaturated sources like olive oil, nuts, seeds, and oily fish, whilst making sure it's not creeping up to the point where it's crowding out the carbs and protein you need for performance and recovery.

5. Fruit, Veg, and Fibre Aren't Optional

These can be the first things to get pushed aside when life gets busy during championship season, but they're crucial for your gut health, immunity, and long-term durability as an athlete.

If you're serious about performing well consistently, recovering optimally, and staying healthy through a tough training and match schedule, don't neglect them.

6. Hydration Keeps Things Flowing

Hydration affects your digestion and how efficiently nutrients and oxygen get delivered to your working muscles.

As a simple recommendation, drink to thirst, and add some extra around your sessions and matches, particularly in warm weather or if you're a heavy sweater.

7. Food First, But Not Food Only

Once you've addressed the food side of things, supplements can be a useful addition to fill gaps or provide a further performance boost, but they should never be the starting point.

Fuelling Match Week

With those general principles in place, match week itself deserves some specific attention.

Carb-loading: In the day or two before the match, increase your carbohydrate intake so that you're heading into game-day with your glycogen stores topped up.

Pre-match meal: Use this to top up your fuel further, sticking to foods and amounts you already know you can digest well.

Match day isn't the time to experiment.

During the game: Right before and during the match, simple carbohydrates and fluids can provide some extra fuel and hydration while you're actively using it.

After the game: Shift your focus to recovery, getting in some protein to support repair, carbohydrates to replenish what you've used, and fluids to rehydrate.

Get these fundamentals right, and you'll go into championship fuelled, recovered, and ready to perform to your potential.
