What is the best way to improve your power and performance on the bike?

What is the best way to improve your running economy and efficiency?


Is it:

  • Sweet Spot or Tempo training?

  • Do you need to focus on higher volume?

  • What intervals will you need to move that performance needle?

The answer is it depends, but with INSCYD you can identify these.

INSCYD is for all athletes.

INSCYD will benefit your training schedule and performance with both a scientific foundation and precise predictability.

With INSCYD you’ll get full picture of your physical capacities and also a prediction of your training and racing outcomes.


The performance you are looking for is composed of a variety of components and metrics, but if you only focus on FTP, heart rate zones, or keep training only according to your Rate of Perceived Exertion, you’ll miss accuracy and efficiency.


For example, with INSCYD you can finally understand the interactions between your aerobic system and your fuelling needs. Do you wonder, “How much should I consume per hour in order to maintain my performance?” With INSCYD, you'll know.


INSCYD takes into account, and connect to one another, the most important metrics for training purposes:


  • VO2max

  • Anaerobic threshold

  • Lactate accumulation and recovery

  • Fat and carbohydrates combustion

  • Recovery

  • VLamax (or glycolytic capacity)


Each of the above metrics measured by INSCYD is critical to performance and remember, each sport performance is predictable and can be broken down to these fundamental elements.

Take VLamax, for example. Although you might have never heard of it, VLamax. It is the single most important measurement to enhance your performance. VLamax is the maximum production of lactic acid in your blood and gives you a complete understanding of your anaerobic metabolism (which yes, is crucial in endurance events, too!). VO2max is aerobic, now we know the anaerobic piece, which turns out to be at least as important.

















Dan Lorang, Coach of Jan Frodeno, Anne Haug

Your really know what you need to work on if you know your VLamax

With the help of the INSCYD software I have been able to cater my training to my own unique energy systems, and tailor that plan to be efficient at the races and durations that I want to excel at.

David Tilbury-Davis, Professional Triathlon Coach

The more we can understand how an athlete does what they are capable of doing the better we can focus what they need to do to get better and this is why after months of assessing and testing with INSCYD I am happy to partner with them to ensure I am doing my utmost to get the best out of the athletes I work with.
