FILE - In this Aug. 29, 2012, file photo, Lance Armstrong talks to supporters prior to a run on Mont Royal Park in Montreal. Armstrong was diagnosed with cancer in 1996. Within minutes of Armstrong announcing he would step down as chairman of Livestrong, the foundation he created to support people with cancer, his longtime endorser Nike issued a statement saying it would be cutting sponsorship ties with the cyclist amid allegations of doping. Armstrong is said to be worth around $100 million, but most sponsors dropped him after USADA's scathing report _ at the cost of tens of millions of dollars.
