How it works
What it does
Analyzes your body weight, sweat rate, event duration and gut tolerance to set carb (g/h), sodium (mg/h) and fluid (mL/h) targets for each phase of the race.
How it works
An LLM trained on current sports-nutrition guidance generates a personalized hourly timeline with specific product recommendations and pacing for carb intake.
Why it works
Built on the same protocols used by pro IM and marathon athletes. Eliminates the bonk and the GI distress that comes from over- or under-fueling.
Common questions
How accurate is the AI nutrition plan?
The plan is built on current sports-nutrition guidance (60–90 g carbs/h, 500–1000 mg sodium/L sweat, individualized by body mass and sweat rate). It's an excellent starting point — fine-tune in training based on your gut tolerance and conditions.
Which races does it cover?
Marathon, half marathon, Ultra (>4h), Olympic-distance triathlon, 70.3 / Half IM, and full Ironman. The plan adjusts carbs, sodium and fluid per hour based on duration and your inputs.
What if I have dietary restrictions or a sensitive gut?
Tick the GI-sensitive box and the plan caps carbs at the lower end and recommends multi-source carbs (glucose+fructose) to ease absorption. Swap any product for an equivalent that fits your diet — carb/sodium/fluid targets are what matter.
Should I practice the plan in training?
Always. Nothing new on race day. Run your last 2–3 long workouts at race pace using the exact gels, drinks and timing the plan recommends.
Does it account for heat?
The base plan assumes moderate conditions. Add your expected sweat rate (use the sweat-sodium calculator) and the plan scales fluid + sodium accordingly. For >85°F races, increase fluids ~15% and slow target pace.
