ELI5: Explain Like I'm 5

Gert-Jan Theunisse

Gert-Jan Theunisse was a professional cyclist who rode bicycles really fast for a living. He was born in the Netherlands and loved to ride his bike everywhere. He became very good at it and won many races.

Sometimes, when people ride bikes really fast for a long time, they may take medicine to help them not get tired and perform better. This is not allowed and is called doping. Gert-Jan Theunisse was accused of doping during his career and was punished for it.

Even though he made a mistake and did something wrong, he was still a really good cyclist and won lots of races. But it’s important for all athletes to be honest and follow the rules, even if it’s hard sometimes.
