The Rain That Sticks

World Run Day

Begun in 1999 to benefit local charities worldwide, the World Run event this year solely benefits world hunger, specifically the U.N.'s World Food Programme. Run anywhere you'd like in Portland for as long as you'd like or sign up as a "Virtual Runner" and only double-click your mouse. Either way, a great cause! Register at runday.com. $20. Easy.
