Armstrong riled by Kornheiser's anti-cyclist rant

Mar 19, 2010 - 12:27 AM WASHINGTON(AP) -- Lance Armstrong says he's going on Tony Kornheiser's radio show to discuss their differences about cycling.

The seven-time Tour de France champion tweeted repeatedly Thursday about Kornheiser's comments last week on ESPN980 that criticized people who ride bikes on streets, including the tongue-in-cheek line: "They dare you to run them down, and then when you do, they get angry."

Armstrong posted on his Twitter feed: "Disgusting, ignorant, foolish. What a complete ... idiot."

Later, Armstrong wrote that he spoke with the former Washington Post columnist and "Monday Night Football" talker, "who's very sorry 4 his comments."

Armstrong said he'll be on the show Friday.
