While many 5-kilometer race participants may have become accustomed to running on the paved streets and sidewalks, Lake Lanier Islands Resort offers a unique twist: racing at night with Christmas-themed lights guiding the path. The Lanier under the Lights 5K will begin at 5:45 p.m. Nov. 15 and 16 at 7000 Lanier Islands Parkway in Buford. Registration for Saturday’s race is closed after the maximum number of participants was reached Oct. 25.
