Discover your unique biological profile to unlock your best

Track your biomarkers over time to build a personalised picture of how your body is responding to training, racing and recovery.

At Forth Edge, we understand the importance of collecting multiple scientific datapoints. More information means better training decisions and a more tailored approach.

Every athlete is different, and mapping your biomarkers over time can help you identify your own personal ‘normal’. From here, you can more accurately track your progress, looking in detail at how your body responds to changes in training and nutrition.


How often should I test?

We recommend testing every three months to build up the most accurate picture of your own biomarker profile. By testing regularly you can see how your profile changes throughout the season and the impact of differing training load and recovery times, as well as changes you may make to your diet.

With our Forth Edge subscription packages, you’ll be sent a test kit automatically at the chosen intervals throughout the year. All you need to do is complete the sampling, send it back and check your app for your updated biomarker results.

What are the advantages of regular testing?

Athletes biomarker levels are often different to the general, non-athlete population, and can also vary between individuals. A variation outside of the ‘average’ biomarker reading may be insignificant for one person, or greatly significant for another. By collecting multiple datapoints you can scientifically identify your own personal biomarker profile. It’s only by determining the Critical Difference Threshold, or CDT, for an individual, can our experts decide whether a significant physiological change has happened.

When you’re talking about sports where marginal gains mean everything, this type of detail is important.

The more regularly you test, the more accurate the picture of your performance and health, and the greater the ability to identify issues before they become problems. 

Created by our team of sports-science experts, our biomarker profiles are designed to optimise endurance, power and strength.
