MCRRC Run Under the Lights

MCRRC Run Under the Lights is a 5K run/walk held at Seneca Creek State Park in Gaithersburg, Maryland. The event begins at 6:15 pm and concludes by 8:00 pm. The race takes place within Gaithersburg’s Winter Lights Festival, with participants moving through the park after dark amidst over 380 illuminated vignettes and 65 animated displays. The course utilizes the park roads, which are closed to regular traffic for the duration of the event, though emergency and race-management vehicles retain access. The Montgomery County Road Runners Club, in collaboration with the City of Gaithersburg, organizes this race. The format accommodates both runners and walkers, not exclusively competitive racers.
