Fuel Trial
Create a mixed box across brands and formats. Test it in training and learn what you tolerate.
Build a trial box →FuelSelect Lab
Test what works. Pack what fits.
Build a fuel trial box for a sensitive stomach—or plan food for a whole expedition group where every person can have different food rules and energy targets.
FuelSelect does not calculate nutritional requirements. In the Trip Builder, you set each person’s own daily energy target and can add as much extra food as you want.
Two ways to use the Lab.
Test products now. Build smarter packs later.
Trip Builder
Add people, set individual food rules, find compatible products and build an editable group pack.
Plan a trip pack →Start with a proven question.
Use a preset as a shortcut, then change anything you want in the builder.
Sensitive Stomach Starter
Explore products with explicit low-FODMAP or other gut-focused positioning in the catalogue.
Fructose-Free Trial
Compare manufacturer-declared fructose-free endurance products across brands.
Savoury Endurance Test
Try less-sweet and savoury options when sweet fuel stops sounding appealing.
High-Energy Trekking Test
Explore calorie-dense expedition meals before committing to a full multi-day food plan.
Carnivore Trail Protein
Find explicitly carnivore-positioned or animal-based protein products for hiking, trekking and recovery.
Fuel Trial Builder.
Choose the activity and food rules. FuelSelect deliberately mixes formats and brands so your trial actually teaches you something.
Build your trial.
The box is a testing shortlist—not a medical test.
Why mixed formats? A useful trial should compare different approaches—not eight versions of the same gel.
Your trial box.
Choose your rules and build a box.
Trip Builder.
Plan for one person or a whole group. Every person can have a different target, diet and set of food rules.
Describe the trip.
Then add the people who are coming.
People
Per-person targets: FuelSelect does not estimate calorie requirements for adults or children. Enter the daily target you want to plan around, or leave it blank and use the builder as a product/quantity planner.
