Dicks-A-Thon: Conceived as a challenge between twin brothers, the Dick’s-A-Thon has grown into Seattle’s premiere marathon event. Participants must run to five different locations of the iconic Dick’s Drive-In and eat something off the menu, like burgers, fries or shakes, at each stop. Dick’s-A-Thon is the origin story of a wacky run that has evolved into a beloved race with 650 participants, a fundraiser and a memorial to one of its mountaineering founders.
