A Philanthropy Today summary on Monday of an article in The New York Times incorrectly described fund-raising efforts by Lance Armstrong for his foundation. He started raising money through his yellow Livestrong bracelets 16 months before he retired from cycling. Since he left cycling, he has raised $100-million for his charitable foundation, and only a small portion of that comes from the bracelets, according to foundation officials. The money is used not solely to finance cancer research but also to help people who have survived cancer as well as advocacy efforts to improve the health-care system.
