Same data your watch already has
Start from the session
Tie fuel to how long you’re out and how hard you’re going — so the plan matches real life, not a textbook.
Carbs · fluid · sodium · race week
Fuel for the session on your calendar — not a generic calorie slide rule.
Find your fuelant
You already respect the training plan. fuelant is the same idea for bottles and pockets — clear checkpoints tied to duration, effort, and race-week chaos.

Long day, same problem
If you’d never test gear race morning, don’t wing nutrition either
The legs get repeat miles. The stomach needs them too — carbs per hour you can hold, fluid you’ll actually drink, salt when it’s roasting, caffeine only if you want it. Under stress, you won’t run a spreadsheet in your head.
fuelant is here to hand you a calm sequence: what happens before the start, between aid stations, and when it gets ugly late.
Three moves: anchor the day, lay out the bottles, run the checklist.
No “platform vision” — just the same rhythm you use for training: decide context, dial details, execute when it counts.
Carbs · fluid · salt · caffeine
Lay out the bottles
A timeline: when to sip, when to eat, when to add salt — not a wall of numbers to decode on mile 40.
Checkpoints, not spreadsheets
Follow it when you’re cooked
Simple before/after cues you can follow when focus is gone — like splits on your watch, but for fueling.
What we obsess over
The boring, important stuff — carried the way endurance folks already think about bottles, sweat, and race morning.
Session-first
The workout sets the plan
Duration and effort come from the day you’re training — not a generic calorie target that ignores the hard Tuesday on your calendar.
Rehearsed, not improvised
Train your gut like you train pace
Step carbs and fluid up over weeks so race morning feels familiar — fewer surprises when your head is already full.
Where you already live
Web for planning, phone at the line
Build and adjust on a bigger screen. When it’s go-time, the same protocol is in your pocket — one source of truth.
Beside your tools
Plays nice with the stuff you already use.
We’re not replacing your training log. We’re the fueling layer next to it — optional hooks when you want less copy-paste.
