Along with academics and social service, the athletic program at St. Albans is considered co-curricular and all students are required to participate. St. Albans competes in the Interstate Athletic Conference (IAC), a league of independent schools in the Washington, D.C. area. In addition to fielding varsity teams in 14 sports: cross country, football, soccer, aquatics, basketball, indoor soccer, ice hockey, wrestling, track and field, lacrosse, baseball, tennis, golf, and crew, the school offers the Voyageur Outdoor Experiential Education program in which students can participate in such sports as indoor rock climbing on a climbing wall and white water kayaking. St. Albans rock climbers compete in the Washington Area Interscholastic Climbing League and kayakers no longer participate in interscholastic competition on the Great Falls rapids of the Potomac River, because the other schools decided to stop competing.
