CMS was founded in 2003 and officially incorporated in 2011. We have our roots in group training activities and volunteering for local community events and larger local events such as Eagleman and Ironman Maryland. CMS is the only Multi Sport club located in Dorchester County, Maryland and we are both a USA Triathlon (USAT) and Road Runners Club of America (RRCA) certified club. 

Annually, CMS organizes the Gerry Boyle Firecracker Kids Triathlon for over 100 area youth with proceeds going to both the YMCA and to our Scholarship Program. The CMS Scholarship programs provides 4 scholarships to graduating seniors at North Dorchester and Cambridge-South Dorchester High Schools every year.
