Disgraced cyclist Lance Armstrong is set for two days of early wake-up calls - first to address 4,000 bikers Sunday at a charity ride and then to learn his fate from cycling's global governing body.

Wake-up calls about the harsh penalties for using performance-enhancing drugs appear to have come far too late for Armstrong, or they went unheeded.

Armstrong was set to appear on Sunday morning to speak with riders at the start of the Livestrong Challenge in his hometown of Austin, Texas, as cyclists ride to raise money for the anti-cancer foundation.
