Is this like MyFitnessPal, Fuelin’, or any other macro calendar?

No — and that’s the point. MyFitnessPal, Fuelin’, and macro calculators focus on guiding daily nutrition: what you eat across a full day to meet dietary goals. The Fueling Tool exclusively solves the challenge of defining and quantifying fueling sources for training and racing — setting specific fueling targets and translating those targets to an hourly-serving-by-source recipe for fueling during a workout or race to sustain your performance. Different goal, different variables, different tool.

Do I need to know anything about sports nutrition to use this?

Nope. The Fueling Tool comes with science-backed default targets for carbohydrates, fluids, and sodium, plus guidance on how to use them. You can build a fueling plan right away even if you’ve never thought about race-day nutrition before. As you learn more, you can adjust your targets.

What sports is it built for?

It's primarily designed for endurance sports — running, cycling, and triathlon — where fueling during effort is critical. If you're doing any event lasting more than 90 minutes, this tool is for you.

What do I get with the Free Edition vs what requires a paid membership?

The Free Edition gives you the default source library, research-backed targets, and the ability to build single-use fueling plans — the full planning workflow. A paid Athlete Edition membership unlocks custom sources, personalized targets, the ability to save and print fueling plans, and a place to store sweat test results. The Free Edition is a great place to start.

What happens if I cancel my membership?

If you cancel a paid Athlete Edition membership, your account transitions to the Free Edition membership. Your saved fueling plans, custom sources, and individualized targets will no longer be accessible, but will be saved should you decide to return to the Athlete Edition membership.

Can I use this with my athletes as a coach?

Yes. Many coaches use The Fueling Tool to build personalized fueling plans with or for their athletes, sharing printable versions of plans or giving clients a tool they can refine across a training season. It pairs naturally with Insight CoachPro if you're already using that for athlete management.

How does The Fueling Tool integrate with Insight CoachPro?

If you're already using Insight CoachPro for athlete management, the Fueling Tool is built into the app. Your athletes can use the Free or Athlete Edition of The Fueling Tool so you both can share fueling plans. (coming soon)

the problem

Your training is dialed in. Your fueling isn’t.

You've put in the miles. You've followed the plan. But when it counts most — mile 80 of a century ride, the back half of a marathon, the final leg of a triathlon — your body falls apart. Not because you didn't train hard enough. Because in-workout fueling is a skill, and it's the one skill almost nobody has a real system for.

"Fueling during training and racing is a discrete skill. Winging it is a strategy — just not a good one."

sound familiar?

You've read about carb targets and fluid replacement and sodium balance, but you still don't know how to turn that into a plan for training and racing.

You fade toward the end of nearly every long run or ride because you don't have a consistent plan that's easy to follow.

You rely on a vague notes or memory to track your fueling plans — and it never quite carries over from one event or month or season to the next.

You're constantly trying new things on race day that often don't work out — because you don't have a way to plan and rehearse your fueling strategy in training.

how it works

Three steps. One plan.

Build a complete fueling strategy for any training session or race in minutes.

Build Your Source Library

Start with our built-in library of common fueling sources — drink mixes, gels, chews, bars, electrolytes — with carb, fluid, and sodium values already filled in. Free Edition members use the universal defaults; Athlete and Coach Edition members can also add their own custom sources with exact values for their go-to products.

Set Your Fueling Targets

The Fueling Tool comes loaded with science-backed defaults for carbohydrates, fluid, and sodium — the three variables that drive your performance. Athlete and Coach Edition members can set fully personalized targets based on their individual needs, sweat test results, and workout conditions.

Create Your Fueling Plan

Map out exactly what you'll take in and when for your workout or race. See your carb, fluid, and sodium totals update in real time as you build the plan. Athlete and Coach Edition members can save and print their plans, refine them after each session, and arrive at the start line with a real strategy — not a guess.

who it's for

Built for athletes who go long.

Runners

Whether you're training for your first marathon or chasing a PR in an ultra, fueling is what keeps you going past mile 20 - or 50. Build and rehearse your nutrition strategy in training so it's second nature on race day.

marathon • 1/2 marathon • ultra

Cyclists

On the bike, there's no excuse not to fuel well — and yet bonking is still the most common preventable problem on long rides. Plan your pockets, plan your bottles, and execute from mile one.

gran fondo • century • gravel

Triathletes

Three disciplines means three opportunities to get fueling right (well, two in practice: tough to fuel while swimming) — or wrong. Map a single, coherent strategy across your bike and run to get you to the finish line strong.

sprint • olympic • 70.3 • ironman

Coaches & Practitioners

Use The Fueling Tool with your athletes to build personalized race-day fueling plans they can actually follow. Give clients a tool to own and refine over time — not a static PDF that lives in their downloads folder. Pairs naturally with Insight CoachPro for full-season athlete management.

about

Built by a coach. For athletes. (And coaches.)

Hi, I’m Alison Freeman. I’m a USA Triathlon Level II Certified Coach, and I built The Fueling Tool because I spend a lot of time building individualized, detailed fueling plans with my athletes.

Fueling is complicated. Knowing the carbs, fluid, and sodium you need to consume for your workout or race is just the first step. Finding the perfect recipe of fueling sources to meet those needs requires a virtual Rolodex of fueling products and a spreadsheet to perfectly balance your fueling choices in alignment with your targets.

There are tools that will tell you your daily nutritional needs, and some will even tell you what you need in order to fuel your workouts and races. But none will tell you exactly how to meet those needs. The Fueling Tool is built to provide that detail – to translate theoretical targets into practical fueling plans for training and racing.
