Darien Dash, in its 18th year, is the premier running event in the Chicago suburbs. The route is designed to run exclusively through a suburban setting of residences and parks. Darien Dash will take place on May 6, 2018. The event has experienced tremendous growth every year which led to the addition of a 10K run in 2011.

Darien Dash is organized by the Darien Chamber of Commerce. The event is one of the fundraising functions that the Darien Chamber of Commerce presents each year for the people of Darien and surrounding communities.
