This guys lies are catching up with him. I also saw an article this week from his home town newspaper saying he was lying at RNC.  Now this.

From the article

Vice presidential candidate Rep. Paul Ryan (R-WI) has been forced to admit that he lied in an interview with conservative columnist Hugh Hewitt when he said that he once completed a marathon in under three hours.  According to Huffington Post, Ryan's campaign has admitted to Runner's World magazine that the congressman's claim to have finished a marathon in "two hours and fifty-something" minutes was a fabrication.

In a prepared statement, Ryan blamed a faulty memory of the event.  He claimed to have been corrected by his brother, rather than by reporters from Runner's World, who began asking questions about Ryan's claim when they could not find any record of Ryan running a three-hour marathon in Wisconsin or anywhere else.
