Boxers & Briefs 5k

The Boxers & Briefs 5k is a running event with both an in-person and a virtual 5k option. The in-person race starts at 9 AM on Saturday, March 21, 2026, at the Broadlands Community Center in Ashburn, Virginia.

Participants are encouraged to run "in your boxers and your briefs, over your clothes, under your clothes, or just as your clothes." The event will collect new packages of underwear (boxers, briefs, socks, bras) to donate to a local group supporting those in need.

Finishers receive a choice of a pair of custom cozy slippers or a soft blend long sleeve t-shirt, plus a finisher's medal. The event supports the charity Rocky Cares, a nonprofit dedicated to raising awareness and funding for Ewing sarcoma research. Visit the organization's website for the most recent information.
