Fuel For The Long Miles
Carb periodization, race-day fueling, electrolyte strategy, and post-session recovery — built around your training week. Designed for runners, cyclists, and triathletes who train aerobically and need their nutrition to keep up.
OUTCOME
THE CHALLENGE
Endurance Nutrition Is Not Strength Nutrition
Generic 'athlete' plans treat 90-minute long runs the same as 30-minute lifting sessions. They aren't. The frustrations we hear most:
"Race-day GI issues are killing my results — I need to actually practice my fueling"
"I cramp on hot training days even though I drink water — electrolytes are a mystery"
"Easy days, hard days, race weeks — my nutrition should change, but it never does"
THE SOLUTION
A Plan That Periodizes With Your Training
Carbs scale up for long-ride and long-run days, recovery meals refill glycogen, and race-week protocols are scripted — not improvised at the start line.
WHY IT WORKS
What Endurance-Focused Nutrition Can Support
Sports nutrition science is clear on the patterns that support aerobic performance. Plans are built around them.
Daily carb intake periodized to training load (often 5–10 g/kg/day depending on volume, per ISSN guidance)
Race-day fueling targets of 30–90 g carbs/hour for sessions over 60–90 minutes
Glycogen replenishment in the post-session window (~1.0–1.2 g/kg carbs/hour for ~4 hours when fast recovery matters)
Protein distribution to support training adaptations (~1.4–1.7 g/kg/day for endurance)
Electrolyte planning — sodium especially — for hot or long sessions
Hydration cues built around session length and conditions
Pre-workout fueling structured to support intensity without GI distress
Recovery-day eating patterns distinct from heavy-training-day eating
Race-week carb loading scripted, not guessed, in the final 36–48 hours
HOW IT WORKS
How It Works
Our AI makes healthy eating simple with a personalized, science-backed approach
STEP 01
Share Your Training Block
Tell us your weekly volume, hard-session days, long-run/ride days, race dates, and any GI tolerances or restrictions.
STEP 02
Get A Periodized Carb Plan
Daily carb targets scale with session demand. Long-ride days look very different from rest days — and that's the point.
STEP 03
Practice Fueling Strategy
In-session carb intake, electrolyte plans, and pre-/post-session meals — including race-week and race-day protocols to rehearse.
STEP 04
Adjust By Block
As your build, peak, and taper phases shift, the plan periodizes with them. Race weeks have their own structure.
REAL RESULTS
What Endurance Athletes Want
Themes we hear from runners, cyclists, and triathletes
I keep blowing up at mile 18. My coach says 'fuel better.' I need an actual fueling plan to practice on long runs.
Early user feedback
Marathoner
Goal: practice race-day fueling weekly
On a long ride day I should be eating completely differently than a rest day. Most apps treat both the same.
User story
Cyclist
Goal: carbs periodized to session demand
Race-week nutrition is where I keep guessing. I want a scripted protocol I can actually follow.
Community feedback
Triathlete
Goal: scripted race-week fueling
Your transformation starts here
Train Hard. Fuel Smart. Race Ready.
Periodized carbs, race-day scripts, electrolyte plans, and recovery meals — built around your training week, not a generic athlete template.

WHAT YOU GET
How The Plan Knows Endurance
Built for aerobic training demands — not adapted from a general fitness plan.
Carb Periodization By Day
Long-run/ride days, hard intervals, easy days, and rest days each get different carb targets — matched to training demand
Race-Day Fueling Scripts
In-session carbs/hour and electrolyte timing scheduled for goal races so race day is a rehearsal, not an experiment
Recovery Meals With Real Glycogen Math
Post-session meals are sized to actually refill glycogen — not just 'something with protein'
Hot-Weather & Long-Session Hydration
Electrolyte and fluid cues built into long-session and hot-condition plans
