Built for triathletes
The nutrition app built for triathletes
MAVR reads your swim, bike, and run training and turns it into daily carbs, protein, hydration, and race-day fueling — so you stop guessing and start fueling for sprint, Olympic, 70.3, and Ironman.
Everything you need to fuel your training
Daily fueling for swim, bike & run
MAVR reads your triathlon training calendar and sets carbs, protein, calories, and hydration for every session — easy swims, long rides, and brick days each get different targets.
Built for 70.3 and Ironman race day
Carb-loading protocols, pre-race meal timing, and during-race carb and sodium targets matched to your sprint, Olympic, 70.3, or full Ironman duration.
Long-session and brick fueling
Hour-by-hour carb and fluid guidance for the long rides and brick workouts where most triathletes under-fuel and pay for it later.
Kai, your AI nutrition coach
Log meals by photo or voice and ask Kai what to eat before a brick, how to recover from a hard session, or how to hit your carb target for the day.
Syncs with your triathlon stack
Connect TrainingPeaks, Strava, Intervals.icu, and Apple Health (Garmin, Coros, WHOOP) so your nutrition updates automatically with your training load.
Hydration & electrolytes for long course
Personalized fluid and sodium guidance that scales with heat, intensity, and session length — critical for staying strong in long-course racing.
How it works
Connect your training once, then let MAVR turn every session into specific, timed fueling.
Connect your training — sync TrainingPeaks, Strava, Intervals.icu, or Apple Health.
MAVR builds daily macro and hydration targets that flex with each swim, bike, run, and brick.
Follow timed pre-, during-, and post-session fueling, and get a race-day plan for your next 70.3 or Ironman.
Why athletes switch to MAVR
Targets that change every day
Unlike static calorie counters, MAVR recalculates your fuel from your actual triathlon training load — hard days go up, recovery days scale back.
Three sports, one plan
Most apps treat you as only a runner or only a cyclist. MAVR models the combined demands of swim, bike, and run in a single daily plan.
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 triathletes?
Yes. MAVR is built specifically for endurance athletes and supports swim, bike, and run as primary sports. It turns your triathlon training calendar into daily carbs, protein, hydration, and race-day fueling instead of a single static calorie target.
Does MAVR support 70.3 and Ironman race-day nutrition?
Yes. MAVR recognizes race days on your calendar and builds carb-loading, pre-race meal timing, and during-race carb and sodium targets based on the duration and intensity of your sprint, Olympic, 70.3, or full Ironman.
Can MAVR fuel brick workouts and long rides?
Yes. MAVR provides session-specific fueling, including hour-by-hour carb and fluid guidance for the long rides and brick workouts where triathletes most often under-fuel.
Does MAVR sync with TrainingPeaks and Garmin?
MAVR connects directly with TrainingPeaks, Strava, and Intervals.icu, and integrates with Apple Health — so Garmin, Coros, WHOOP, and Oura data flow in automatically to adjust your nutrition.
How much does the triathlon 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.
