Cycling's self-confessed drug cheat Lance Armstrong says the $100-million lawsuit against him can't undo all of the good that was done over the years.

Former cyclist Lance Armstrong says he "loved" representing the US Postal Service, even as the government sues to get back the millions it spent sponsoring his teams.

After years of legal wrangling, the federal government's $100 million ($A130 million) lawsuit against Armstrong is expected to go to trial later this year.

Speaking on his podcast Tuesday , Armstrong said it was an honour to wear the Postal Service jersey as he competed in Europe and to hear the national anthem played when he won.

But he said the lawsuit "can't undo all of the good that was done all of those years".

Armstrong claims the government made more money in publicity from the sponsorship than the $32 million ($A42 million) it paid his teams.

The Postal Service sponsored Armstrong's team when he won six of his seven Tour de France titles from 1999-2005.

Armstrong later admitted using performance-enhancing drugs and was stripped of those titles.
