Run beyond ordinary
Smart Coaching
Training load
Shows you how your training affects your body and helps you compare the load of different workouts. Continuous monitoring of training load will help you recognize your personal limits and adjust your training intensity and duration according to your targets.
Recovery status
Find the perfect balance between training and rest and get a true picture of your recovery status before getting out there again. Recovery status is based on the cumulative load of all your activities including your training sessions and data on the small activities you do every day. Continuous monitoring of recovery status helps you plan your training so that you avoid over- and undertraining.
Fitness Test
If you're looking to improve your fitness and want to keep up to date with how well you're doing, the smart Fitness Test will tell you exactly what you need to know in just five minutes. By regularly comparing your test results, you can see what progress you are making and how your fitness is improving.
Running Index
If you're looking to keep on top of your running performance you'll find this feature a big help. Regular use over time allows you to see how efficient your running is. Your Running Index score is calculated automatically after every run, based on your heart rate and from the speed data collected from your GPS or stride sensor. A higher reading indicates that you can run faster with less effort. In V800, this feature can also recognize if you're running uphill or downhill.
Training Benefit
Motivating feedback that's delivered straight to you immediately after exercise is something we can all benefit from. So if you want to know the effect of different training sessions, this feature will tell you exactly what you need to know.
Smart Calories
OwnCal is the most accurate calorie counter on the market. It calculates the number of calories expended during a training session based on your weight, height, age, gender, your individual maximum heart rate (HRmax) and how hard you're training.
Activity Guide
Activity Guide shows how active you've been during the day. It also tells you how much you need to do to reach the global recommendations for physical activity. With practical guidance like 'walk for 50 minutes or jog for 20 minutes' you can choose how to reach your daily activity goal. Meet your goal faster with more intense activities or stay active at a slightly more moderate pace throughout the day.
Activity Benefit
Activity Benefit tracks all your active choices during the day and shows how they help you stay healthy. It'll reward you when you've done enough and make you move if there's still a bit missing from your daily activity goal. Activity Benefit gives you daily, weekly and monthly feedback, because the more you move, the greater the health benefits. You can check Upon how you're doing either from your mobile or from the web.
