Endurance quantified
The future of fitness analytics.
Introducing the missing link in exercise science to runners everywhere. The first true measure of aerobic endurance, based on a breakthrough in heart rate analysis resulting from years of pioneering research. Now anyone can easily and above all, accurately measure their endurance on a scale from 0-100%.
Driftline's combination of patent-pending data algorithms coupled with unique analytic capabilities reduces the extraordinarily-complex science and interpretation of endurance down to a single number.
What is endurance?
Endurance reflects fuel efficiency. With higher endurance you will spend less fuel for each mile of running. Endurance mirrors the power of the aerobic energy system.
We're all built different
Where do you stand?
Running is an integral part of many different sports and athletes come in all shapes and sizes. Athletes from different sports can vary widely in terms of running capacity, from the sprinting-type to the endurance-type.
Find out where you stand using the Truezone app or the Time machine.
Accessible to everyone
Lab-grade analytics without the lab.
Traditional fitness testing either requires expensive lab equipment or leaves you lying on the floor, gasping for air or both. With Driftline, you get more accurate results by just going out for a casual run, wearing your personal fitness tracker.
Driftline is presenting a breakthrough in personal fitness monitoring. A patent-pending methodology of heart rate analytics has been designed for the performance analysis and training of recreational and professional athletes, sports teams and even beginners. Using Driftline analytics and your own fitness tracker, the future of fitness analytics is only a glance away.
