“I used to bonk at mile 20 every single race. MAVR helped me dial in my fueling plan for Berlin and I ran a 3:57 — a 14‑minute PR. I finally trust my nutrition on race day.”

MAVR is built for endurance athletes and supports running, cycling, swimming, triathlon, and Hyrox as primary sports — with full sport-specific fueling strategies for each. We also support strength training, HIIT, yoga, pilates, and more. Whether you're training for a 5K, an Ironman, or a Hyrox race, MAVR adapts your nutrition to match the demands of your sport.
MAVR's nutrition engine is grounded in peer-reviewed sports science from researchers like Jeukendrup, Burke, and the ISSN. We combine your basal metabolic rate (BMR) with your active energy expenditure, training volume, workout intensity, and body composition to calculate precise daily calorie and macronutrient targets. Our system also models glycogen availability throughout the day and applies sport-specific fueling protocols — so a long ride gets different nutrition guidance than a strength session.
MAVR connects directly with Strava, TrainingPeaks, Intervals.icu, and Runna to automatically sync your training calendar and workout data. We also integrate with Apple Health, which means any device that syncs to Apple Health — including Garmin, Coros, WHOOP, and Oura — will automatically feed your training data into MAVR for real-time nutrition adjustments.

MAVR recognizes race days on your calendar and adjusts your nutrition accordingly. This includes carb loading protocols in the days leading up to your event, optimized pre-race meal timing, and during-race fueling targets based on the duration and intensity of your race — whether it's a marathon, a century ride, or a triathlon.
Absolutely. MAVR syncs with your training calendar and recalculates your nutrition targets every day. On hard training days, your carb and calorie targets increase to fuel performance. On rest days, they scale back to support recovery. We also provide specific pre-workout, during-workout, and post-workout meal recommendations with precise macro timing.
Most calorie trackers give you a single static daily target. MAVR is fundamentally different — your targets change every day based on your actual training schedule. We don't just count calories; we calculate sport-specific macronutrient needs, time your nutrition around workouts, and adjust dynamically as your training load changes. It's the difference between a generic calorie counter and a sports nutritionist in your pocket.
Yes. MAVR provides personalized hydration recommendations based on your training schedule, workout intensity, and duration. Staying properly hydrated is critical for athletic performance, and MAVR helps you stay on top of your fluid intake throughout the day and around workouts.
