Co-ed flag football is offered on both Lower School Campuses in the winter (January – February) to students in grades 3 – 5. Teams practice twice a week and have regular opportunities for home and away games against many local schools, including Grace Episcopal, Jacksonville Country Day School, Riverside Presbyterian Day School and San Jose Episcopal. The League is part of the North Florida Independent School Athletic Conference (NFISAC).

In addition to playing home and away games at other elementary schools, St. Mark’s and Beaches Campus students have the opportunity to play at Episcopal School of Jacksonville’s Jangro Stadium, located on the Munnerlyn Campus, at the end of the season.

All lower-school athletics have a no cut policy.  The goal is to build skills, promote teamwork, foster a love of the game, and provide a competitive and fun outlet for students to grow and be physically active as part of a healthy lifestyle.
