What to Eat Before HYROX: Race Week to Finish Line

What to Eat Before HYROX: Race Week to Finish Line

Don’t Let Nutrition Be the Limiting Factor for HYROX

You’ve pushed sleds, tossed countless wall balls, and nailed race sims—now ensure your nutrition doesn’t hold you back. HYROX requires power and endurance, so your fuelling strategy must be precise to make or break your race.

Reminder: Good fuelling = better energy, fewer crashes, and a stronger finish.


Race Week: Build Your Energy Stores

 

Focus: Top up, but don’t overthink it


The week before the race

  • Eat a well-balanced, healthy diet.
  • Prioritize foods rich in vitamin C to support a strong immune system.
  • Avoid high-risk foods for food poisoning (e.g., sushi, deli meats, food that has been sitting out of the fridge for more than 2 hours or less if it is hot outside).
  • Consider drinking beet juice for the week leading up to your race to optimize cardiorespiratory efficiency and potentially improve your race day result by 1-3%.
  • See this review for more on the effects of beet juice and this blog for how to incorporate it into your race week regimen.

 

3 Days before the Race

  • Prioritize consistent carbohydrates at meals (think rice, potatoes, bread, pasta, fruit).
  • Keep protein steady for muscle recovery.
  • Don’t dramatically change your diet.
  • Stay well hydrated by drinking water and eating foods rich in electrolytes. Adding some salty foods helps, but don’t go overboard. Some sodium helps your body absorb fluids; too much isn't good for your heart health.

 

24 Hours before the race

  • Choose higher-carb, lower-fibre foods. Skip All-Bran and Metamucil for breakfast. Opt for white bread or white rice over whole grain. This may seem odd if you prefer healthy foods, but your gut will thank you in the middle of the race.
  • Also- avoid heavy, greasy, or risky foods (no, the raw fish in your sushi is not a good idea today).
  • Include sodium and electrolytes.
  • Sip fluids consistently

 

Quick Tip: Aim to arrive at race day feeling fuelled, not stuffed.


Race Morning: Start with Full Energy


3-4 hours before start


Ideal Pre-Race Meal:

  • Easy-to-digest carbs
  • Moderate protein
  • Low fat, low fibre
  • Examples:
    • Bagel + peanut butter + banana
    • Oatmeal + blueberries + milk + juice
    • Toast + eggs + fruit


Hydration:

  • 500-750 ml fluids


Tip: include a sports drink with your pre-race meal.



90-120 Minutes Before Start: The Top-Up


Small Fuel, Big Difference


Choose a carb-rich snack and/or sports drink to top up your liver glycogen stores before the start.

 

Examples:

  • Banana
  • ½ peanut butter sandwich



15 Minutes Before Start

 

It takes a little time for you to absorb the food you eat. Think of the 15 minutes before race start as the start of your HYROX race fuelling. What to consume?:
  • Energy gel and a sports drink top-up.
  • Caffeine if it is something you have tried in training.



During HYROX: Should You Fuel Mid-Race?


Absolutely yes- especially if aiming for peak performance.


HYROX lasts 60 minutes or less for pros, but often 90-120+ minutes for many, so mid-race fueling helps maintain pace and focus. Hybrid racing quickly depletes energy stores as it mixes aerobic and anaerobic work. As such, it is crucial to fuel before and during the race.

 

15 Minutes Before Start

 

It takes a little time for you to absorb the food you eat. Think of the 15 minutes before race start as the start of your HYROX race fuelling. What to consume?:
  • Energy gel and a sports drink top-up.
  • Caffeine if it is something you have tried in training.


Aim for:

  • 30-60 g of carbs an hour
  • Easy-to-digest carbs, protein and fat are not needed
  • Easy-to-carry options
  • Quick-to-eat options

Great choices:

  • Energy gels
  • Fruit pouches
  • Chews
  • Sports drinks- mix your own or use a commercial product. Here are a few examples of ones we love:


Practical tip: Plan exactly what you’ll take and when (e.g. one gel after Station 4, or before the run).


Recovery: Refuel to Recover Faster


Within 30-60 minutes


Prioritize:

  • Carbohydrates
  • 20-30 g of protein
  • Fluids and electrolytes


Why we love this idea:

  • Refuelling soon after racing helps you choose healthy options before potentially moving to alcohol, sweets, or fried foods.


Easy options:

  • Recovery shake- we love Tailwind recovery
  • Chocolate milk
  • Yogurt, muesli, and berries
  • A sandwich and a sports drink



Common Hyrox Nutrition Mistakes


Don’t let these common missteps weigh you down:

  • Underfuelling race week
  • Avoid fried or greasy food the night before—a burger and fries isn’t a good pre-game meal.
  • Also, eating too much fibre the night before- now is not the time for a big kale salad.
  • Forgetting to hydrate consistently and regularly. We don’t want you overdoing it, but be sure to hydrate before getting to the start line.
  • Trying new products on race day- yes, nothing new on race day
  • Waiting until you feel tired to fuel- stick to your schedule and get ahead of your fueling.


Final Takeaway: Practice Your Fuel Plan


Remember: Making HYROX nutrition part of your training ensures you are prepared. Test your eating, drinking, and carrying strategy during race simulations so your race day routine feels automatic.
