Performance testing at Rehamed Heidelberg shows us where we stand before taking on HYROX together.
The countdown is on: on 16 April, blind para judoka Lennart Sass and I will be on the starting line at HYROX in Cologne!
As part of our preparations, we recently had the opportunity to undergo performance testing at Rehamed Heidelberg. Karlos Yacoub, Rehamed’s managing director, kindly made this possible 🙌
Lennart is a blind para judoka, just 26 years old, and an absolute machine in sporting terms — a European champion, among other achievements. The testing very quickly showed just how high his performance level is and how far I am from it 😜 At the same time, it reminded me how valuable it is to take stock regularly. In sport, in business and in life. Where am I now, and where do I actually want to go?
The challenge for our HYROX entry is clear. Lennart cannot see, so we need to coordinate perfectly as a team, find ways to trust each other literally without sight, and get through the workouts together. That is exactly why this performance testing was so important: a starting point we can build on.
That makes it all the more wonderful to have people like this around us. Supportive, professional and caring. A special thank you also to Marcell Stein for his support on site 🫶
Now it is time to train, get used to working together and improve step by step 💪
