Lance Armstrong is being urged to make a full confession of all his involvement in doping by the founder of lobby group Change Cycling Now.

Founder Jaimie Fuller told Reuters on Wednesday that he spoke to Lance Armstrong on the phone last month and urged Armstrong to confess all.

Change Cycling Now includes former Tour de France champion Greg Lemond.

Fuller also said he had exchanged emails with Armstrong after Fuller told the disgraced cycler Armstrong to talk to the U.S. Anti-Doping Agency (USADA) about what he experienced keeping his doping habits a secret.

Last Year, USADA stripped Armstrong of his seven Tour de France titles.

In an interview with Oprah Winfrey, Armstrong admitted that he had taken performance-enhancing drugs before each and every one of his tour victories.

Fuller earlier told the 'Tackling Doping In Sports 2013' conference that he had wanted to believe Armstrong was clean.

Fuller told the conference, "The thing that upset me most about Lance was not the doping. We know how prevalent the doping was, how entrenched it has been in the culture of cycling,"

"What upset me most all the other things that surrounded him, the way he abused people, the way he just climbed all over people, the win at all cost. I had a conversation with him not long ago and I said to him it's going to get worse for him before it gets better.

"I think he's a bit delusional. He's got to come clean; he's got to tell everything. We didn't see that on Oprah Winfrey, what we saw on Oprah Winfrey was the convenient truths. And when it was inconvenient we didn't get the truth. That includes not protecting other people he's protecting. He needs to show a bit of contrition," Fuller concluded.

Indeed, it does seem that Armstrong may not quite understand how hurt the public was by his doping and lies.

In an interview with Texas Monthly, Armstrong compared his situation to former president Bill Clinton's.

Armstrong called Clinton a hero of his and compared his own apology on Oprah for taking performance-enhancing drugs to the one Clinton gave for having an affair with White House Intern Monica Lewinsky.

Armstrong told the paper, "Ultimately, people forgive and forget and remember the good stuff you did. [Clinton is] a hero of mine. He's a tough guy...and 10 years later, he's president of the world. It can be done."
