TGS has a wide complement of athletic facilities—a 6-court tennis facility, 3 full-size natural grass fields, a field house with competition sized basketball court, and the Corsica River with 2 docks for our sailing and rowing programs.

TGS hosts thirteen varsity team sports, five fitness programs, and two junior varsity sports teams. Athletics is an essential part of the Gunston Experience, promoting healthy lifestyles, camaraderie, and competition.
