Endurance Plus Test

By Forth Edge

Our Endurance Plus blood profile is specifically designed for endurance athletes such as triathletes, cyclists and long distance runners. It brings together a wide range of biomarkers that help athletes to manage the delicate balance between training load, recovery and nutrition. 

Markers in this profile include: 

  • Key hormones e.g. testosterone & cortisol 
  • Haematocrit
  • B12, iron, vitamin D
  • Analysis of over 20 performance biomarkers 

The information will help you to optimise performance by giving you insight into your body's response to training load and identify areas where you may need to improve your nutrition.

Results will be reviewed by a sports medicine doctor who is also an expert in RED-S (Relative Energy Defiency Syndrome). 

This test is an essential tool for both professional and recreational athletes who have a high training load.
