Built for Hyrox athletes
The nutrition app built for Hyrox
Mavr reads your lifting, running, and sim sessions and turns them into daily carbs, protein, and hydration — plus a race-day plan for Open, Pro, Doubles, and Relay. One plan for a hybrid week, not a runner's plan with a gym day bolted on.
Everything you need to fuel your training
Lift days, run days, sim days — different targets
Mavr reads your calendar and sets carbs, protein, calories, and hydration per session. A heavy sled session and a 10 km run don't get the same plate.
Race day for Open, Pro, Doubles & Relay
A light carb-load, race breakfast timing, and in-race fuel anchored to the eight stations — sized to your division and target finish.
Protein that protects your strength
Running volume climbs in a Hyrox block. Mavr holds protein at 1.8–2.2 g/kg so you keep muscle while the engine grows.
Kai, your AI nutrition coach
Log meals by photo or voice and ask Kai what to eat before a sim, how to recover from a double day, or how to hit today's carb target.
Syncs with your watch and your gym
Connect Apple Health (Garmin, Coros, WHOOP), Strava, or TrainingPeaks. Gym sessions and runs both count — nothing gets lumped in as a walk.
Hydration for hot venues
Fluid and sodium guidance that scales with heat and session length — indoor arenas in summer are warmer than most athletes plan for.
How it works
Connect your training once, then let Mavr turn every session into specific, timed fueling.
Connect your training — Apple Health, Strava, or TrainingPeaks — and set Hyrox as your sport.
Mavr builds daily macro and hydration targets that flex with each lift, run, sim, and double day.
Follow timed pre-, during-, and post-session fueling, and get a race-day plan for your next Hyrox.
Why athletes switch to Mavr
Hybrid, not runner-only
Most endurance apps see you as a runner. Mavr models strength and running load together, so a heavy sled day raises protein and a long run raises carbs.
Targets that change every day
Unlike static calorie counters, Mavr recalculates your fuel from your actual sessions — double days go up, rest days scale back.
Grounded in sports science
Mavr's engine is built on peer-reviewed research (Jeukendrup, Burke, ISSN) and models glycogen availability throughout your day.
Frequently asked questions
Quick answers about how Mavr fuels your training and racing.
Is Mavr a good nutrition app for Hyrox?
Yes. Hyrox is a supported sport in Mavr. It turns your lifting, running, and sim sessions into daily carbs, protein, hydration, and race-day fueling instead of a single static calorie target.
Does Mavr plan Hyrox race-day nutrition?
Yes. Mavr recognizes race days on your calendar and builds a light carb-load, race-morning meal timing, a pre-start top-up, and in-race carb targets sized to your expected finish time and division.
What should I eat before a Hyrox sim?
Treat a sim like race day: a low-fibre, low-fat breakfast of about 1–1.5 g of carbs per kilo 2–3 hours before, a 20–30 g carb top-up 30 minutes out, and one gel on the run out of a station if the session runs past 75 minutes. Mavr times all of this for you.
Will Mavr detect my Hyrox gym sessions?
Yes. Strength and functional sessions from Apple Health, Garmin, Coros, WHOOP, Strava, and TrainingPeaks all come through, and Mavr classifies anything labelled Hyrox as a hybrid session so it gets the right carb and protein targets.
How much does the Hyrox nutrition app cost?
Mavr offers a free trial with full access. Mavr Pro adds AI Food Analysis, Voice Meal Logging, and dynamic AI meal generation that adapts to your training calendar every day.
