ASPEN, Colo. (AP)--Lance Armstrong says he's more at peace now than he has been in a decade.

In his first interview since the U.S. Anti-Doping Agency disciplined Armstrong with a lifetime ban from professional cycling and vacated his seven Tour de France titles, he said, "Nobody needs to cry for me. I'm going to be great."

Still, his ego was bruised after being beaten by 16-year-old Keegan Swirbul at the Power of Four mountain bike race Saturday. Armstrong finished second, nearly five minutes behind the lanky teenager.

Soon after crossing the finish line and skidding to a stop, Armstrong chatted for a few minutes before saying, "OK, I'm going to go eat a cheeseburger."

He's leaning toward not following through with his plan to run a trail marathon Sunday.
