MCRRC Run Under the Lights

Welcome to Run Under the Lights!

The City of Gaithersburg, in partnership with the Montgomery County Road Runners Club, invites all runners and walkers to participate in a 5K Run/Walk in the magical setting of Gaithersburg’s Winter Lights Festival at Seneca Creek State Park. Winter Lights features more than 380 illuminated vignettes and 65 animated displays. Runners and walkers will utilize the roads through the Park during the race. Roads will be closed to traffic except for Emergency Vehicles and vehicles required for race management.

The 2023 event will be limited to 900 registered participants.  In past years, the race has sold out in a matter of days or sometimes hours!   Our participation limit will be strictly enforced due to the terms of our permits.  Once registration is full, we are unable to offer exceptions.  Thank you for your understanding

If you are unable to participate in the race, please consider volunteering - Volunteers will also have the rare chance to view the light display on foot and are very much needed in order to provide a memorable experience for all!
