The Ultimate Gravel Race Fueling + Nutrition Guide

When it comes to fueling your body for a demanding gravel race, you’re performing a high-stakes balancing act.

Gravel races come with their own set of challenges: long days in the saddle, unpredictable terrain, and often limited aid station support. That’s why the most reliable and effective strategy is to bring your own nutrition — especially one you’ve trained with and trust. Relying on whatever the race provides can lead to unnecessary guesswork and gut surprises.

At INFINIT, we believe in eliminating the variables. Our all-in-one drink mixes are designed to make fueling simple, predictable, and personalized. You can go entirely liquid — no bars, gels, or chews needed — and give your body exactly what it needs to perform, without the stress of wrappers or reaching for food while navigating rough terrain.

Endurance athletes often burn 400–1000+ calories per hour, and while traditional wisdom held that the body could only absorb around 250–350 calories per hour (up to 400 at the high end), emerging research is now challenging that limit. Athletes are increasingly pushing carbohydrate intake to 90–120+ grams per hour, with impressive results.

While this approach may be too aggressive for recreational or mid-pack athletes without preparation, those who properly "gut train" can experience significant gains in performance, reduced fatigue, and improved recovery times. The key is balancing this higher intake with proper hydration and electrolyte replacement—fueling in a way your body can absorb and sustain.

Whether your goal is simply to finish feeling strong or to go all-out for a PR, here’s your step-by-step guide to race day fueling:

1. Estimate Your Time on Course

Use the course map, elevation profile, and terrain type to make a realistic estimate. Look at past finish times if available or ask others who’ve done similar races. Be sure to account for aid station stops and hike-a-bike sections.

2. Figure Out Your Fluid & Electrolyte Needs

Hydration can make or break your day. In long, hot races, dehydration can cause cramping, foggy thinking, and even nausea. Avoiding that starts with knowing your sweat rate.

Your sweat rate depends on a variety of factors including genetics, heat, humidity, clothing, and intensity. While you can use general guidelines (e.g., 16–20 oz/hr in cooler weather and up to 45+ oz/hr in heat), the best way to dial this in is through a personalized sweat test.

Pro tip: INFINIT offers Sweat Test Nutrition Coaching with certified sports dietitians to help determine your precise fluid and sodium needs. It's the most accurate way to ensure you're replacing what you're losing.

3. Determine Your Carbohydrate Needs

Plan to take in at least 60–90g of carbs per hour, and up to 120g if your gut can tolerate it.

When glycogen runs low, performance plummets. You feel sluggish, foggy, maybe even dizzy—and the dreaded “bonk” kicks in. Liquid nutrition is an easy and effective way to get in calories without the hassle of opening wrappers or chewing while riding.

Want to go fast? INFINIT’s PREMIUM Fructose Fuel formulas are engineered for high-carb intake with minimal gut stress—offering 90g and 120g of carbs per serving to help you maximize speed and performance.

Start fueling early and stick to consistent intervals. Even if you're not feeling hungry yet, your body needs time to absorb nutrients before you start digging deep.

4. Plan Your Aid Strategy

Not all races have well-stocked aid stations—or any aid stations at all. That’s why self-sufficiency is king in gravel racing.

Instead of hoping the race offers something that works for your gut, bring nutrition that’s dialed in and tested. Carry your INFINIT mix in bottles or a hydration pack, and preload extra powder in resealable bags for quick bottle refills if needed.

5. Stock Your Bike

Start with at least 2 bottles of carb + electrolyte drink on the bike.

One of the easiest ways to fuel for long races is to concentrate your bottles and carry plain water in a hydration backpack — Take a swig of your fuel concentrate, and wash it down with a couple gulps from your backpack. Simple and requires minimal time with your hands off the bars.

Always carry more than you think you'll need. If you drop a bottle, get a flat, or face unexpected delays, you’ll be glad you packed extra. If space allows, use a frame bag or jersey pocket to store an extra bottle or a few pouches of mix.

Some races offer drop-bag services; utilizing these offerings can help reduce your carrying weight by allowing you to grab a couple fresh bottles along the way.

6. Practice Fueling in Training

Rough terrain, group dynamics, and technical sections can make fueling tricky. Train like you race—practice drinking and fueling on group rides, on dirt, and under race-like conditions. The more familiar you are with your routine, the smoother it’ll go on race day.

7. Plan for the Unexpected

• Dropped bottle? Use tight bottle cages and secure your setup before race day.
• Crash or mechanical? Know where aid stations are (if any) and bring more fuel than you think you’ll need.
• Riding with friends? Consider carrying an extra bottle or two in case someone else bonks or forgets to pack enough.

8. Personalize Your Plan

Every athlete is different. Goals are different. Sweat rates are different. Fueling should be too.

That’s why we offer free one-on-one nutrition consults with our Formulation Specialists to help you dial in the exact plan that’s right for you. Whether you’re going for a podium or just want to cross the finish line strong, we’ll help you customize a formula and strategy that fits.

9. Go Out, Have Fun, and Crush It

Gravel racing is a multi-faceted challenge. But with the right plan—and the right fuel—you can eliminate the guesswork, focus on the ride, and race your best.
