Join the Sugarloaf Mountain Athletic Club

Membership Information

Anyone interested in participating in and supporting recreational or competitive running in Western MA is invited to join the Sugarloaf Mountain Athletic Club (SMAC).

Founded in 1972 by Charlotte Lettis and Tom Derderian, Sugarloaf is open to runners of all ages and abilities. SMAC is a member of both USA Track & Field, the premier national governing body of running in the United States, and the Road Runners Club of America (RRCA), the oldest and largest distance running organization in the U.S.

SMAC’s purpose is to promote running as a recreational activity and a competitive sport by providing and supporting running and racing opportunities to all runners in the Valley. We welcome all ages and levels of experience, from young runners who are just learning about the joys and benefits of the sport, to more seasoned runners who can tell a race story or two.
