Dozens of brave runners didn't let the freezing temperatures stop them from hitting the streets of D.C. for a good cause.

Members of D.C. Capital Striders, one of the region’s largest running groups, participated in its annual Holiday Lights Run.

They were decked out in festive holiday clothing with a few added layers to handle the cold.

Proceeds from the run supported St. Jude's Hospital and donated toys supported the Salvation Army.
