Jingle Bell RO Ck & Run

Jingle Bell RO Ck & Run is a holiday-themed road event in Ashburn, Virginia, on December 12, 2026. Three distances all start at 9:00 AM: a 10K (6.2 miles), a 5K (3.1 miles), and a 1-mile run. The single start time keeps things simple for groups, since everyone lines up together and picks the distance that matches their fitness or their mood on the day.

For a runner who has spent the fall on shorter races, the 10K is a sensible year-end step up; a six- to eight-week block with one longer run of 5 to 7 miles and one faster session per week is enough to arrive ready. The 5K suits first-timers and anyone chasing a quick time before the winter base phase, while the 1-mile keeps children and walkers in the mix. A 9:00 AM start in Northern Virginia in December calls for gloves and a hat at the line, so dress in layers you can peel off once you are moving.
