Almost hard to believe that actor Charlie Sheen is “A” doing anything for charity, and “B” running.

The former “Two and a Half Men” star is planning to run or walk next month to support the Pancreatic Cancer Research’s Dash For Detection challenge – a  3.1 mile course.

He tweeted:

 ”Hello Chicago!! I’ll be there to scoot… Walk or Run! Dash for detection for pancreatic cancer research June 2 in Chicago!”

How do you think Charlie will fair in the challenge?  I’m sure he’ll be walking most of the way.
