How MAVR Calculates Your Workout Fuel Plan (Without Spreadsheets)
Spreadsheets can be “correct” and still fail in real training. Here’s the MAVR approach: pick the workout that matters, set a carb target you can execute, and pair it with hydration and meal timing that makes sense.
Quick Answer
MAVR generates a workout fuel plan by looking at your upcoming training, choosing the session where fueling matters most, setting a personalized carbs-per-hour target, rounding it into a simple schedule, and pairing it with hydration guidance that can use your sweat profile.
Spreadsheets can be “correct” and still fail in real training.
Why? Because most athletes don’t fail on math — they fail on execution: starting too late, guessing hydration, or trying a brand-new strategy on race day.
MAVR’s goal is simple: turn your training calendar into a fueling plan you can actually do, without obsessing over numbers.
Why Spreadsheets Fail (Even If the Math Is Right)
- Training changes week-to-week, but spreadsheets are static.
- Timing is everything — “hit X carbs today” isn’t actionable mid-workout.
- Your gut limits what you can absorb at intensity.
- Most tools ignore hydration and sodium, which often drives late-workout crashes.
What MAVR Uses (In Plain English)
| Feature | Why it matters | What you see in MAVR |
|---|---|---|
| Upcoming workouts | Fueling needs depend on the session | A plan for the workout that matters most |
| Duration + intensity | Drives carb needs and GI tolerance | A carbs/hour target + simple timing |
| Sport context | Running and cycling differ in execution | A schedule that matches how you train |
| Body weight + units | Scales targets appropriately | Targets that fit you (metric/imperial) |
| Sweat profile (optional) | Personalizes fluid + sodium | Hydration ranges + electrolyte notes |
How a Target Becomes a Schedule
A good plan doesn’t require mid-workout math. MAVR converts your target into practical “do this at minute X” guidance.
- Start after the workout settles (often ~10–25 minutes).
- Repeat a simple interval (often ~15–25 minutes).
- Use practical increments so it matches real servings.
Hydration: Better With Sweat Data, Still Useful Without It
Two athletes can run the same pace and have completely different sweat and sodium losses. That’s why a one-size-fits-all hydration number fails.
If you’ve done sweat testing, MAVR uses it to improve fluid and sodium recommendations. If not, you still get evidence-based guidance and sensible ranges.
Frequently Asked Questions (FAQ)
Is MAVR’s workout fuel plan “AI generated”?
MAVR uses your training context plus evidence-based rules to generate consistent, repeatable fueling guidance. The goal is reliability — not random tips.
Why does MAVR sometimes focus on my long run instead of my next workout?
Because long sessions are where fueling mistakes cause the biggest performance and recovery problems. Planning for the key workout improves consistency.
Why are the recommendations rounded instead of super precise?
Precision doesn’t help if you can’t execute it. Rounding makes it easier to match real servings (gels, chews, drink mixes) and follow a plan under fatigue.
What if my workout duration is only an estimate?
MAVR can still plan from estimated durations. The plan is designed to be helpful even when workout data isn’t perfect.
