The 10th annual World Run Day, an international day of running and charitable giving, will be held Sunday, November 9. To participate, you need to do two things. Go out and run some distance, any distance, on the 9th. Then donate to your favorite charity. You'll help promote the benefits of running, while also helping others.

You can register online for World Run Day ($17.99, which gets you an official T-shirt), as well as search for events in your area.

Or simply decide to get out the door and run that day, whether it's for a mile or an ultra, and save that $17.99 to go toward your donation. Because if you really want to help others you can do so without buying another cotton T-shirt.
