Spinnathon
Mad? Slightly. With some colleagues and almost 100 other people we did a spinnathon. I've been spinning for 3 hours. Some did even 6 hours. Spinning? Sweating on a home trainer, listening to a heavy beat and an empowering instructor. We did it for fund raising for the Richard Krajicek Foundation and of course also for the challenge. The challenge to go further than before, to feel your limits. Just before I started I got interviewed. The journalist wanted to know what is important for a successful ride. Well, drink enough and pay attention to your heart frequency.
First hour: it’s easy. A normal exercise. Just keep the heart beat a bit lower. 85% of the maximum heart rate is ok. Above it the amount of lactic acid in your blood raises. Above 90% is exhausting the body. One will not even complete 1 hour. At 95% not even 15 minutes. The exercise becomes anaerobic. Sport is something you do with your brains as well.
Second hour. The start is OK. But the beat is too fast. I’m riding my own ride.
Third hour. I’m feeling great. It’s endorphin. Can’t trust the feeling in my muscles. Can’t rely on emotions either. I’m feeling high, runners high. There is no coach here. My reason and the heart rate monitor on my watch are my guides. 94%! Well there only 15 minutes left. Just keep going. A cold trembling? Am I getting too hot? Slow down, 10 more minutes. Finally it’s 4 o’clock. Another song? Ok, cooling down. We did it. Time for muscle stretching. Ai ai ai….
