Proper hydration is the backbone of endurance performance. Whether you're tackling a marathon, an Ironman, or a century ride, your fluid and electrolyte strategy can make or break your race. But not every athlete sweats the same amount or prefers the same flavors. That's where TORQ Build-a-Box of Hydration Sachets comes in—a flexible system that lets you create a personalized hydration kit tailored to your needs.

In this guide, we'll walk you through how to use the Build-a-Box to select the right hydration sachets, mix them correctly, and time your intake for race day. You'll also learn how to pair these sachets with other TORQ products like energy gels and recovery drinks for a complete fueling plan.
What Is the TORQ Build-a-Box of Hydration Sachets?
The TORQ Build-a-Box is a customizable selection of hydration sachets that allows you to choose your preferred flavors and formulations. Instead of buying a pre-packed box, you handpick each sachet based on your taste and performance needs. This is ideal for athletes who want to avoid flavor fatigue or those who need specific electrolyte profiles for different race conditions.
Each sachet contains TORQ's 1:1 ratio of maltodextrin and fructose, delivering a dual-transport carbohydrate system that maximizes energy absorption. Plus, they include essential electrolytes like sodium, potassium, and magnesium to replace what you lose through sweat. The Build-a-Box is available in a range of flavors, from classic citrus to berry blends, so you can mix and match to keep your taste buds engaged during long events.
- Choose from multiple flavors to avoid taste fatigue.
- Each sachet provides 500ml of ready-to-drink hydration with 1:1 carbs and electrolytes.
- Perfect for training, racing, or everyday hydration support.
How to Select Your Hydration Sachets for Race Day
Start by assessing your sweat rate and race duration. For a half-marathon, you might need 1-2 sachets, while a full Ironman could require 8-10. Consider the weather: hot and humid conditions increase electrolyte loss, so choose sachets with higher sodium content if available. Also, think about flavor—if you're using energy gels like the Naked Flavourless Energy Gel, you might prefer a fruity hydration sachet to complement it.

The Build-a-Box lets you order exactly what you need. For example, you could include a mix of citrus and berry sachets for variety, or stick to one flavor if you know it works for you. Don't forget to test your chosen flavors during training to ensure they sit well on the move. Many athletes also pair hydration sachets with the TORQ 6 Energy Jellies Sample Pack for a diversified fuel strategy.
- Calculate your fluid needs based on sweat rate and race distance.
- Test flavors in training to avoid surprises on race day.
- Mix with other TORQ products like gels and jellies for complete fueling.
Step-by-Step: Mixing and Using Your Hydration Sachets
Mixing a TORQ hydration sachet is straightforward. Empty the contents into a clean 500ml water bottle, add water, shake well, and it's ready. For best results, use cool water and shake vigorously to dissolve all powder. If you prefer a stronger or milder taste, adjust the water amount slightly, but keep the carbohydrate concentration within the recommended range for optimal absorption.
During exercise, sip your hydration drink regularly—about 150-250ml every 15-20 minutes. This helps maintain fluid balance and energy levels without overwhelming your stomach. For longer events, alternate between hydration sachets and plain water to avoid overconsumption of carbs. After your race, use a recovery drink like the Robust & Fruity Flavour TORQ Vegan Recovery to replenish protein and glycogen stores.
- Mix one sachet with 500ml water; shake well.
- Sip 150-250ml every 15-20 minutes during exercise.
- Alternate with plain water in extreme heat or long events.
Tips for Personalizing Your Hydration Plan
Everyone's hydration needs are different, so use your training sessions to dial in your plan. Start by weighing yourself before and after a long workout to estimate sweat loss. For every kilogram lost, aim to consume 1-1.5 liters of fluid. Adjust your sachet count accordingly. Also, consider your stomach sensitivity—some athletes prefer a more diluted mix, while others need the full concentration for energy.
The Build-a-Box also allows you to experiment with different electrolyte balances. If you're a heavy sweater, look for sachets with extra sodium. For cooler days, a standard mix may suffice. Keep a log of what works and what doesn't, and don't be afraid to tweak your order for the next race. Pairing your hydration with a pre-race carb-load dessert, such as the Carb-Load Dessert - Rhubarb & Custard Flavour, can further optimize your glycogen stores.
- Use pre- and post-workout weigh-ins to estimate sweat loss.
- Experiment with dilution and electrolyte levels in training.
- Combine with carb-load desserts for peak glycogen stores.
Personalizing your race hydration with the TORQ Build-a-Box of Hydration Sachets gives you control over flavor, electrolyte intake, and carbohydrate delivery. By testing your choices in training and following a consistent sipping schedule, you'll stay fueled and hydrated from start line to finish.
