Lance Armstrong scrapped his much-publicized plan to set up an independent drug-testing program on Wednesday because of high costs and nearly impossible logistics.

When Armstrong announced his comeback last year, the seven-time Tour de France winner said he wanted to prove he was clean, and was teaming with anti-doping expert Don Catlin, who would test him and post the results online.

But Catlin told The Associated Press that after months of negotiations, both sides realized the program wasn't workable this year.
