I have had some challenges since my crash. Something that still troubles me. I've been looking for something to help me reach my former level. GRASPOR is a revolutionary tool that I hope can help med on my journey. I like working alone, and i believe GRASPOR's data will help me control my efforts and make sure I train smart.

Mathias Norsgaard, Movistar Team

I have been the 6th best Zwift rider for a while now. I feel that I have optimized every part of my training and preparations, but I am looking for the final marginal gains to reach my goal of becoming the world’s best Zwift rider! I hope that the opportunities and insight GRASPOR gives me can help me find the last gains to achieve this goal.

Nicklas Amdi Pedersen, 3rd at the Esports World Championships 2020

"I have chosen to use GRASPOR as a part of my journey back from a concussion, which has impacted me since the summer of 2019. The ability to control my intensity based on the muscle oxygen level, instead of zones is very helpful in my situation. I believe it will make a difference for me, as I can clearly see how far I can push my body each day."

Christina Siggaard, Lotto Soudal Ladies
