Donations to Lance Armstrong’s cancer charity skyrocketed on the day after the cycling legend abandoned his challenge to charges that he used performance-enhancing drugs, Reuters reports.

The Lance Armstrong Foundation, better known as Livestrong, received 400 donations worth $75,000 on Friday, 20 times what it took in on Thursday, when Armstrong made his announcement and was stripped by the U.S. Anti-Doping Agency of his seven Tour de France titles.

Supporters of the foundation, based in Austin, Tex., “respect Lance’s decision and I think they just want to move on,” Doug Ulman, the chief executive of Livestrong, said of the outpouring.

Mr. Armstrong continues to deny allegations of cheating but said Thursday that he was tired of fighting the nonprofit anti-doping body, which had reportedly lined up several witnesses, including former riders and staff members of Mr. Armstrong’s cycling team, to testify against him.
