Hiiro is a marathon-training app that creates a fully personalized and adaptive plan based on your needs and fitness. It uses Rate of Perceived Exertion (RPE) for training, not pace or heart rate. You pick a marathon from a stylish race catalog, get workouts synced to your Apple Watch, and chat with an AI coach who guides and motivates you.

Hiiro is designed specifically for marathon training, so it focuses on preparing you for full marathon races. It does not offer plans for half marathons, 10km, or 5km distances.

Just answer a few onboarding questions in the app, pick your target marathon from the race catalog (or add your own), and Hiiro will instantly create a personalized training plan for you. It’s quick, easy, and fully tailored to your needs.

Yes, you can add your own marathon if it’s not in the catalogue. Once you've gone through the catalogue you will be given an option to enter your race details and Hiiro will build your training plan around your chosen event.

You’ll need to provide your target marathon, current fitness level, weekly schedule, height, weight, age, and your recent longest run (if any). Hiiro uses this info to build your plan and never shares it with third parties.

Hiiro does not support Garmin integration at the moment, but it is coming to Hiiro soon!

You’ll need an Apple Watch to use Hiiro since workouts sync directly to the watch for easy tracking and guidance during your marathon training.

Hiiro does not sync with Strava. You’ll need an Apple Watch to track your workouts and follow your training plan in the app. However, you can still use Strava independently and sync your workout to it.

Yes you can reset the race. Go to your profile and tap on the target race. There you will find an option to reset it. Tap on reset button and follow the instructions to select your new race.

You don’t need to set a goal time in Hiiro. The app builds your training plan using your fitness and runs by Rate of Perceived Exertion (RPE), not by a specific target finish time. Just follow the effort levels, and you’ll get stronger and faster naturally to reach your best potential!

Depending on your current fitness level we suggest different training time. If your current long run is over 21 km, you can get to a marathon on three months, while for complete novice runners it can take 30 weeks.

If your BMI is over 30, Hiiro will not create a training plan for safety reasons. Marathon training is very demanding, and starting with a lower BMI helps reduce health risks and keeps you safe on your running journey. We recommend starting with walking regularly and coming back to running when BMI reduces below 30.

You need to select at least 4 training days because consistent running is key for safe and effective marathon preparation. Hiiro’s plans are built to help you progress and reduce injury risk by making sure you train often enough. Minimum of 4 days a week is crucial closer to the race, while at the start of your journey we'll give you less training days a week.

No that is not necessary. Minimum of 4 days a week is crucial closer to the race, while at the start of your journey we'll give you less training days a week if that fit your current level.

Choosing a day for your long run helps your training stay structured and balanced. Hiiro uses this info to place your key workout each week, making sure you recover well and build endurance safely. You can also change the day later by talking to the AI coach.
