How to Make Your Own Carb Mix for Cycling: The Ultimate DIY Guide

Did you know commercial sports drinks can cost up to five times more than a DIY version? Learn how to make your own carb mix for cycling and fuel your performance for a fraction of the cost, with ingredients tailored to your needs.

Quick Summary

This guide details how to make DIY cycling carb mixes using specific carbohydrate ratios, highlighting the benefits of customization and cost-effectiveness.

Key Points

• Cost-Effective Fuel: DIY carb mixes are significantly cheaper than commercial sports drinks, saving you hundreds over a season.

• Personalized Ratios: Customize the maltodextrin-to-fructose ratio (e.g., 2:1 or 1:0.8) to optimize carbohydrate absorption for different ride intensities.

• Control Ingredients: Avoid artificial additives and tailor flavor and electrolytes to your specific taste and dietary needs, reducing the risk of GI distress.

• Adjust for Intensity: Use a less concentrated mix (e.g., 60g carbs/hr) for easier rides and a denser mix (e.g., 90-120g/hr) for longer or more intense efforts.

• Easy to Source: Bulk ingredients like maltodextrin, fructose, and sodium citrate can be purchased affordably from online supplement stores.

• Environmental Bonus: Using reusable bottles and flasks reduces reliance on single-use plastic packaging from pre-made gels and mixes.

Why Make Your Own Carb Mix?

For many cyclists, fueling can become a significant expense. The "carb revolution" has pushed elite and amateur athletes alike to consume higher and higher amounts of carbohydrates per hour, sometimes up to 120 grams or more. Relying solely on expensive pre-packaged gels and drinks for daily training can quickly add up. Creating your own mix offers a budget-friendly, customizable, and often healthier alternative, letting you train as you race without breaking the bank.

The Benefits of a DIY Approach

• Cost-Effectiveness: Making your own mix from bulk ingredients like maltodextrin and fructose can result in massive savings. Some estimates show homemade versions costing as little as 5% of commercial alternatives.
• Customization: You can precisely control the carbohydrate ratio, sweetness, and electrolyte content to match your unique fueling strategy and taste preferences.
• Stomach Friendliness: By selecting pure, high-quality ingredients, you can reduce the risk of gastrointestinal (GI) distress, avoiding the artificial flavors and fillers found in some commercial products.
• Reduced Waste: Reusable bottles and gel flasks eliminate the single-use plastic waste from wrappers and sachets.

The Science of Carb Ratios: Maltodextrin and Fructose

To maximize carbohydrate absorption during prolonged exercise, it's beneficial to combine different types of sugars. Your body uses two primary intestinal transporters for glucose and fructose. By using both pathways simultaneously, you can absorb more carbohydrates per hour and reduce the risk of GI issues.

Understanding the Ratios

• Maltodextrin (Glucose): A fast-digesting, flavorless carbohydrate that uses the SGLT1 transporter. It provides immediate energy and is the foundation for most high-carb mixes.
• Fructose: A fruit sugar that uses the GLUT5 transporter and is metabolized in the liver. It's sweeter than maltodextrin, so a smaller proportion can significantly impact the taste.
• 2:1 Ratio (Maltodextrin:Fructose): The traditional standard for endurance fueling, allowing for absorption of up to 90g of carbs per hour. It's a great starting point for most riders and sessions lasting 1-3 hours.
• 1:0.8 Ratio (Maltodextrin:Fructose): The modern, high-performance standard used by many elite athletes. It can enable absorption of up to 120g of carbs per hour for ultra-endurance events, but requires gut training and can increase the risk of GI issues if you're not adapted.

DIY Carb Mix Recipes

The Standard 2:1 Performance Mix (Up to 90g/hr)

This versatile and stomach-friendly mix is perfect for most endurance rides and races up to a few hours long.

Ingredients:

• 1kg Maltodextrin powder
• 500g Fructose powder
• 100g Sodium Citrate powder
• No-sugar-added flavouring (e.g., True Lemon, Kool-Aid powder, fruit drops)

Directions:

1. Thoroughly mix the maltodextrin, fructose, and sodium citrate in a large, airtight container. Label it clearly.
2. To make a 90g/hr bottle (approx. 750ml), combine 60g of the bulk mix with 600ml of water.
3. Add 1-2 scoops of your desired flavouring and shake well until dissolved.
4. For longer rides requiring more hydration, you may need additional electrolyte powder. A good starting point is 1-2g of sodium citrate per 750ml bottle.

The High-Carb 1:0.8 Endurance Mix (Up to 120g/hr)

For seasoned endurance athletes looking to maximize carbohydrate intake on long or intense rides. This is not recommended for beginners.

Ingredients:

• 1kg Maltodextrin powder
• 800g Fructose powder
• 100g Sodium Citrate powder
• No-sugar-added flavouring

Directions:

1. Mix the dry ingredients in an airtight container, ensuring they are well combined.
2. To make a 120g/hr bottle (approx. 750ml), mix 120g of this blend with 600ml of water and flavouring.
3. Shake vigorously. The solution may be more viscous than the 2:1 mix due to the higher carb concentration. It's crucial to sip regularly and stay well-hydrated to avoid GI issues.

The Simple 'Real Food' Natural Mix

An incredibly simple and cost-effective option using common pantry staples. While the ratio is a fixed 1:1, it can be a great option for less intense or medium-duration rides.

Ingredients:

• Table sugar (sucrose, a 1:1 glucose:fructose blend)
• Table salt
• Citrus juice (for flavour)

Directions:

1. For a 500ml bottle, mix 30-40g of table sugar with a pinch of table salt.
2. Add a squeeze of fresh lemon or lime juice for flavour.
3. Fill the bottle halfway with water, shake until dissolved, and top up. This delivers an easily digestible carb boost with simple electrolytes.

Frequently Asked Questions

What is the best maltodextrin to fructose ratio for my cycling mix?

For most rides (1-3 hours), a 2:1 maltodextrin:fructose ratio is effective and gentle on the stomach. For experienced athletes targeting maximum carb intake on ultra-endurance rides, a 1:0.8 ratio can push absorption up to 120g/hr.

How do I add electrolytes to my homemade carb mix?

You can add table salt, but sodium citrate is often preferred for its smoother taste. A good starting point is 1-2 grams of sodium citrate per 750ml bottle, adjusting based on sweat rate and temperature.

What is a good natural carb source for cycling?

Table sugar (sucrose) provides an effective 1:1 glucose-to-fructose ratio and is a cheap, readily available option for a homemade mix. Maple syrup is another natural option that provides a similar carb profile.

Will a homemade carb mix cause stomach issues?

When done correctly, a homemade mix can be gentler on the stomach as it avoids artificial additives and you can train your gut to tolerate the specific carb ratios. Start with lower concentrations and practice your fueling strategy during training.

How much carbohydrate should I consume per hour while cycling?

For rides over 90 minutes, start with a target of 60-90g of carbs per hour. On longer, more intense days, you can increase this amount, potentially up to 120g/hr with an adapted gut and the right carb ratio.

Where can I buy bulk ingredients for my DIY mix?

Online supplement and chemical suppliers like BulkSupplements.com often stock maltodextrin, fructose, and sodium citrate in bulk quantities. Check brewing supply stores or online marketplaces like Amazon as well.

How long will a homemade carb mix last?

A dry, pre-mixed batch of carb powder will last for several months if stored in an airtight container in a cool, dry place. Mixed drinks should be consumed within 24 hours for freshness.
