"In light of the current circumstances Stephen has made it clear he doesn't want a mistake he made two decades ago to affect the work of Cycling Australia to take the sport forward," Mueller said.

"I would like to personally thank Stephen for his immense contribution to the sport in a volunteer capacity. When his professional cycling career ended he became a tireless worker for the sport and for almost 15 years has freely given up his time as an advocate for the rights of athletes and to promote and develop the sport in Australia."

In a letter to the board of Cycling Australia, Hodge said his position in the sport was untenable.

"Prior to the CA Board meeting on the 16 October 2012 I advised Graham Fredericks [chief executive] and Klaus Mueller that during a stage of my career as a professional cyclist I took performance enhancing drugs — a decision I am not proud of," Hodge wrote.

"I am sorry I did it. It was wrong. I apologise unreservedly to CA, my family, friends, colleagues and cycling fans."
