Canadian star cyclist Ryder Hesjedal says he ``chose the wrong path'' after reports suggesting he was involved in doping emerged Wednesday.
Excerpts from a new book by former Danish rider Michael Rasmussen say Hesjedal was shown how to use performance-enhancing drugs at the start of his career.
Hesjedal said in a statement that the ``mistakes'' happened more than 10 years ago when he was still a mountain biker and they were short-lived.
Hesjedal did not explicitly say he took performance-enhancing drugs, but in the contrite statement he apologized ``for my part in the dark past of the sport.''
``I will always be sorry,'' he said.
Excerpts of Rasmussen's autobiography ``Yellow Fever'' released in Danish newspaper claim that he taught Hesjedal how to use EPO, a banned substance used in blood doping.
