Now in its fourth year, this unique after dark 5K will raise funds for the Georgetown School. Participants will receive a t-shirt and reusable LED flashlight and are encouraged to bring their glow-in-the-dark accessories and clothing to light up the night. The route starts and ends at the school and will take runners and walkers through beautiful downtown Georgetown and around East Bay. Money raised benefits the school’s scholarship fund to help families pay tuition and other costs.

The Georgetown School, 1200 Highmarket St. Saturday, 7:45 p.m. $30. (843) 520-4359, thegeorgetownschool.org
