πŸƒβ€β™€οΈ How to Fuel in preperation for a Road Marathon – Easy Tips for Peak Performance

Training for a road marathon is more than just the miles you log. How you fuel your body before race day plays a huge role in your performance. Here's a simple guide to help you eat and drink smart in the lead-up to your big day.


βœ… 1. In the Build-Up: Eat Well, Stay Hydrated

  • Stick to your usual meals – no need to switch things up last minute.

  • Focus on fresh, whole foods – avoid fast food and heavily processed snacks.

  • Aim for balanced meals with carbs, protein, and healthy fats.

  • Hydration is key – sip water throughout the day, every day.

🧠 Top Tip: Get used to drinking small amounts often to stay consistently hydrated.


πŸ“† 2. Days Before the Marathon

  • Your goal now is to maximise recovery and energy stores.

  • Drink a Night Fuel in the evenings – it helps nourish your muscles while you sleep.

  • Sip an Energy Fuel during the day to give your system an extra boost.

  • Travelled for the race? Use energy drinks with vitamins and minerals to help fight fatigue.

  • If you’re flying, hydrate well in the air to avoid travel-related dehydration.


πŸŒ„ 3. Race Day Morning: Keep It Light but Powerful

  • Skip anything too heavy or greasy – no fry-ups or mega portions.

  • Choose a calorific but easy-to-digest breakfast like Morning Fuel.

  • Add a banana or a few seeds if you need something extra.

  • On the go? A FeelGoodBar is perfect – packed with energy, light on the stomach.

πŸ§ƒ After breakfast, sip some Energy Fuel and keep it with you en route to the start line.
⏱️ Top start line tip? Have a Sports Jelly 15 minutes before the race for a final energy boost.


πŸ•’ 4. Got a Long Wait Before the Start?

  • Big races often mean hanging around before the gun goes off.

  • Bring a small bar to nibble on or keep a Sports Jelly ready.

  • These are easy to digest and give a pre-race energy top-up without weighing you down.
