The Jingle Bell Rock & Run takes place on Saturday, December 14th at the area’s premier gathering place – One Loudoun in Ashburn, Va! Celebrate the holidays with us! Run the 5K/10K race, or have your little ones hop straight out of bed and onto the 1K course for the Jammie Jingle (fun run)! Then, enjoy loads of fun at the after party – let your kids meet with Santa, hear the sounds of the season, enjoy some tasty treats and have the family take part in the festivities that will be sure to put you in the holiday spirit!
