Lang road for the Swiss team IAM Cycling between 2013 and 2016, having previously competed for the continental team Atlas.

Operation Aderlass has implicated athletes in several sports, including skiing and cycling, as being involved alleged involvement in a doping ring.

It followed Austrian police conducting raids in the Austrian village Seefeld and in Erfurt in Germany last year.

A statement from the 35-year-old’s Twitter account confirmed involvement in Aderlass.

“My name is Pirmin Lang, I am 35 years old and I resign from professional cycling today," Lang's statement read.

“I’ve started racing bikes 20 years ago, I’ve been a professional cyclist from 2013 to 2017 and I am nowadays a sports director.

"A couple of years ago I've initiated a structure to develop young cycling talents in my country.”

"I wanted a team because I wanted to protect them,” the statement continues.

“Protect them from the wrongdoings I could witness and experience during my professional career.

"To protect them from the mistakes I did, the mistakes I cannot keep as a personal secret anymore.

“The mistakes that I am revealing today.

“I've cheated through my professional career as a cyclist.

"I was part of the 'Aderlass' network.

“I lied and I am responsible for my actions.

“I regret it."

Lang, who competed at the 2014 Vuelta a España, has left his role as manager and directeur sportif at Swiss Racing Academy (SRA).

The Swiss team, which competes at continental level, confirmed Lang had resigned from his post.

"The SRA announces the immediate departures of Pirmin Lang as head of sport," a team statement read.

"Mr Lang tendered his resignation after being interviewed by police investigating historical doping offences in professional cycling.

"He has confessed to cheating during his career as a professional cyclist, engaging in activities that are at odds with everything the SRA team stands for.

"We are appalled to discover that Mr Lang behaved in this manner during his career.

“We emphasise that there has been no suggestion of any illegal practices at SRA.

"Mr Lang has apologised for his behaviour."

Cyclists Kristijan Durasek, Kristijan Koren, Borut Božič, Alessandro Petacchi, Georg Preidler and Stefan Denifl have all been banned as part of Operation Aderlass.

Durasek, Preidler and Denifl received four-year bans following anti-doping cases.

Two-year bans were given to Bozic, Božič and Petacchi.

Austrian cyclist Christina Kollmann-Forstner was also suspended by the International Cycling Union (UCI) in May as part of an investigation into "potential anti-doping rule violations".

The UCI had cited Operation Aderlass as part of its reasoning for seeking collaboration with the International Testing Agency.
