CHICAGO — The president of a cancer charity founded by Lance Armstrong insists that the organization will persevere in the wake of the cyclist’s admission that he used performance-enhancing drugs.

The Livestrong Foundation’s president, Doug Ulman, is scheduled today to deliver what the organization described as a “major `State of the Foundation’ speech” in Chicago.

“Our success has never been based on one person,” Ulman said in remarks prepared for the annual gathering of Livestrong charity leaders, grantees and others. “Will the Livestrong Foundation survive? Yes. Absolutely, yes. Hell, yes.”

Armstrong stepped down as chairman of the charity in October, saying he didn’t want his association to damage the foundation’s ability to raise money and continue its advocacy programs on behalf of people with cancer.

Originally called the Lance Armstrong Foundation, the cyclist created the organization in Austin, Texas, a year after he was diagnosed with testicular cancer that had spread to his brain and lungs.

Armstrong admitted during an interview with Oprah Winfrey this year that he used performance-enhancing drugs when he won seven straight Tour de France titles.
