Lace up your running shoes and get ready to celebrate -- Sunday, November 8 is World Run Day 2009!

World Run Day was conceptualized in 1999 by veteran runner Bill McDermott, who told Active.com, "The idea was an international day of charity, built around running. I thought if we could just focus on one day, wouldn't that be great for all of us?" The first actual World Run Day was the following year, and after September 11, 2001, McDermott refocused his energy into the holiday to make it something people all over the world could take part in.

The idea of World Run Day is that, rather than having to run in a specific organized event to raise money for a cause, people can raise money and just go out for a run on their own. If you'd like to participate in a group event, Active.com has a list of World Run Day events near you.

A day just for running and helping charity that doesn't romanticize a marathon? Nobody can object to that!
