Stephen Hodge has resigned as vice-president of Cycling Australia (CA) after admitting to doping during his professional career.
Hodge turned professional in 1987 and raced in the European peloton until retiring in 1996.
He was elected vice-president of CA in 2007.
CA President, Klaus Mueller released a statement today accepting Hodge's resignation and thanking his contribution to the sport.
"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," said Mueller.
"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."
Hodge in a letter to the board of CA, said his position in the sport was untenable.
"Prior to the CA Board meeting on the 16 October 2012 I advised Graham Fredericks [CEO] 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."
Hodge said that he abstained from any meeting or discussion to do with the termination of the contract on Wednesday of CA's professional coordinator and national men's team coach, Matt White.
White admitted to doping while riding with Lance Armstrong's US Postal professional team from 2001 to 2003.
